W=1 builds warn that the data written to 'tc_name' is truncated for theoretical strings such as "channel-2147483646". Solve this problem by replacing snprintf() with scnprintf() so that the return value corresponds to what was actually written. In practice, the largest string that will be written is "channel-8", and the return value is not actually evaluated. Instead, this patch ultimately removes the warning without unnecessarily increasing the size of 'tc_name' from 10 bytes.

…m hierarchy Without explicitly setting a parent for the watchdog device, the device is registered with a NULL parent. This causes device_add() (called internally by devm_watchdog_register_device()) to register the device under /sys/devices/virtual, since no parent is provided. The result is: DEVPATH=/devices/virtual/watchdog/watchdog0 To fix this, assign &pdev->dev as the parent of the watchdog device before calling devm_watchdog_register_device(). This ensures the device is associated with the Portwell EC platform device and placed correctly in sysfs as: DEVPATH=/devices/platform/portwell-ec/watchdog/watchdog0 This aligns the device hierarchy with expectations and avoids misplacement under the virtual class.

The Elan eKTH8D18 touchscreen controller is an I2C HID device with a longer boot-up time. Power sequence timing wise it is compatible with the eKTH6A12NAY, with a power-on delay of at least 5ms, 20ms out-of-reset for I2C ack response, and 150ms out-of-reset for I2C HID enumeration, both shorter than what the eKTH6A12NAY requires. Enumeration and subsequent operation follows the I2C HID standard. Add a compatible string for it with the ekth6a12nay one as a fallback. No enum was used as it is rare to actually add new entries. These chips are commonly completely backward compatible, and unless the power sequencing delays change, there is no real effort being made to keep track of new parts, which come out constantly. Also drop the constraints on the I2C address since it's not really part of the binding.

USB3 devices connected behind several external suspended hubs may not be detected when plugged in due to aggressive hub runtime pm suspend. The hub driver immediately runtime-suspends hubs if there are no active children or port activity. There is a delay between the wake signal causing hub resume, and driver visible port activity on the hub downstream facing ports. Most of the LFPS handshake, resume signaling and link training done on the downstream ports is not visible to the hub driver until completed, when device then will appear fully enabled and running on the port. This delay between wake signal and detectable port change is even more significant with chained suspended hubs where the wake signal will propagate upstream first. Suspended hubs will only start resuming downstream ports after upstream facing port resumes. The hub driver may resume a USB3 hub, read status of all ports, not yet see any activity, and runtime suspend back the hub before any port activity is visible. This exact case was seen when conncting USB3 devices to a suspended Thunderbolt dock. USB3 specification defines a 100ms tU3WakeupRetryDelay, indicating USB3 devices expect to be resumed within 100ms after signaling wake. if not then device will resend the wake signal. Give the USB3 hubs twice this time (200ms) to detect any port changes after resume, before allowing hub to runtime suspend again.

…sume
Shawn and John reported a hang issue during system suspend as below:
- USB gadget is enabled as Ethernet
- There is data transfer over USB Ethernet (scp a big file between host
and device)
- Device is going in/out suspend (echo mem > /sys/power/state)
The root cause is the USB device controller is suspended but the USB bus
is still active which caused the USB host continues to transfer data with
device and the device continues to queue USB requests (in this case, a
delayed TCP ACK packet trigger the issue) after controller is suspended,
however the USB controller clock is already gated off. Then if udc driver
access registers after that point, the system will hang.
The correct way to avoid such issue is to disconnect device from host when
the USB bus is not at suspend state. Then the host will receive disconnect
event and stop data transfer in time. To continue make USB gadget device
work after system resume, this will reconnect device automatically.
To make usb wakeup work if USB bus is already at suspend state, this will
keep connection for it only when USB device controller has enabled wakeup
capability.

This reverts commit ffd603f. Commit ffd603f ("usb: gadget: u_serial: Add null pointer check in gs_start_io") adds null pointer checks at the beginning of the gs_start_io() function to prevent a null pointer dereference. However, these checks are redundant because the function's comment already requires callers to hold the port_lock and ensure port.tty and port_usb are not null. All existing callers already follow these rules. The true cause of the null pointer dereference is a race condition. When gs_start_io() calls either gs_start_rx() or gs_start_tx(), the port_lock is temporarily released for usb_ep_queue(). This allows port.tty and port_usb to be cleared.

A race condition occurs when gs_start_io() calls either gs_start_rx() or gs_start_tx(), as those functions briefly drop the port_lock for usb_ep_queue(). This allows gs_close() and gserial_disconnect() to clear port.tty and port_usb, respectively. Use the null-safe TTY Port helper function to wake up TTY.

xhci_reset() currently returns -ENODEV if XHCI_STATE_REMOVING is set, without completing the xhci handshake, unless the reset completes exceptionally quickly. This behavior causes a regression on Synopsys DWC3 USB controllers with dual-role capabilities. Specifically, when a DWC3 controller exits host mode and removes xhci while a reset is still in progress, and then attempts to configure its hardware for device mode, the ongoing, incomplete reset leads to critical register access issues. All register reads return zero, not just within the xHCI register space (which might be expected during a reset), but across the entire DWC3 IP block. This patch addresses the issue by preventing xhci_reset() from being called in xhci_resume() and bailing out early in the reinit flow when XHCI_STATE_REMOVING is set.

This reverts commit 6ccb83d. Commit 6ccb83d ("usb: xhci: Implement xhci_handshake_check_state() helper") was introduced to workaround watchdog timeout issues on some platforms, allowing xhci_reset() to bail out early without waiting for the reset to complete. Skipping the xhci handshake during a reset is a dangerous move. The xhci specification explicitly states that certain registers cannot be accessed during reset in section 5.4.1 USB Command Register (USBCMD), Host Controller Reset (HCRST) field: "This bit is cleared to '0' by the Host Controller when the reset process is complete. Software cannot terminate the reset process early by writinga '0' to this bit and shall not write any xHC Operational or Runtime registers until while HCRST is '1'." This behavior causes a regression on SNPS DWC3 USB controller with dual-role capability. When the DWC3 controller exits host mode and removes xhci while a reset is still in progress, and then tries to configure its hardware for device mode, the ongoing reset leads to register access issues; specifically, all register reads returns 0. These issues extend beyond the xhci register space (which is expected during a reset) and affect the entire DWC3 IP block, causing the DWC3 device mode to malfunction.

Export anon_inode_make_secure_inode() to allow KVM guest_memfd to create anonymous inodes with proper security context. This replaces the current pattern of calling alloc_anon_inode() followed by inode_init_security_anon() for creating security context manually. This change also fixes a security regression in secretmem where the S_PRIVATE flag was not cleared after alloc_anon_inode(), causing LSM/SELinux checks to be bypassed for secretmem file descriptors. As guest_memfd currently resides in the KVM module, we need to export this symbol for use outside the core kernel. In the future, guest_memfd might be moved to core-mm, at which point the symbols no longer would have to be exported. When/if that happens is still unclear.

drvdata::gpiods is supposed to hold an array of 'gpio_desc' pointers. But the memory is allocated for only one pointer. This will lead to out-of-bounds access later in the code if 'config::ngpios' is > 1. So fix the code to allocate enough memory to hold 'config::ngpios' of GPIO descriptors. While at it, also move the check for memory allocation failure to be below the allocation to make it more readable.

This WA is applicable to BMG as well. Note that this is a GSC WA and we don't load the GSC on BMG, so extending the WA to BMG won't do anything right now.

…b/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes
Fixups
- Fixed raw pointer leakage and unsafe behavior in printk()
. Switch from %pK to %p for pointer formatting, as %p is now safer
and prevents issues like raw pointer leakage and acquiring sleeping
locks in atomic contexts.
- Fixed kernel panic during boot
. A NULL pointer dereference issue occasionally occurred
when the vblank interrupt handler was called before
the DRM driver was fully initialized during boot.
So this patch fixes the issue by adding a check in the interrupt handler
to ensure the DRM driver is properly initialized.
- Fixed a lockup issue on Samsung Peach-Pit/Pi Chromebooks
. The issue occurred after commit c9b1150 changed
the call order of CRTC enable/disable and bridge pre_enable/post_disable
methods, causing fimd_dp_clock_enable() to be called
before the FIMD device was activated. To fix this,
runtime PM guards were added to fimd_dp_clock_enable()
to ensure proper operation even when CRTC is not enabled.

Commit <4f1492efb495> ("iommu/vt-d: Revert ATS timing change to fix boot
failure") placed the enabling of ATS in the probe_finalize callback. This
occurs after the default domain attachment, which is when the ATS cache
tag is assigned. Consequently, the device TLB cache tag is missed when the
domain is attached, leading to the device TLB not being invalidated in the
iommu_unmap paths.
Fix this by assigning the CACHE_TAG_DEVTLB cache tag when ATS is enabled.

The i2c/piix4 change is a effectively a revert of the commit 7e173eb ("i2c: piix4: Make CONFIG_I2C_PIIX4 dependent on CONFIG_X86") but that required moving the header out from arch/x86 under include/linux/platform_data/ Summary: - amd/isp4: Improve swnode graph (new driver exception) - asus-nb-wmi: Use duo keyboard quirk for Zenbook Duo UX8406CA - dell-lis3lv02d: Add Latitude 5500 accelerometer address - dell-wmi-sysman: Fix WMI data block retrieval and class dev unreg - hp-bioscfg: Fix class device unregistration - i2c: piix4: Re-enable on non-x86 + move FCH header under platform_data/ - intel/hid: Wildcat Lake support - mellanox: - mlxbf-pmc: Fix duplicate event ID - mlxbf-tmfifo: Fix vring_desc.len assignment - mlxreg-lc: Fix bit-not-set logic check - nvsw-sn2201: Fix bus number in error message & spelling errors - portwell-ec: Move watchdog device under correct platform hierarchy - think-lmi: Error handling fixes (sysfs, kset, kobject, class dev unreg) - thinkpad_acpi: Handle HKEY 0x1402 event (2025 Thinkpads) - wmi: Fix WMI event enablement" * tag 'platform-drivers-x86-v6.16-3' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86: (22 commits) platform/x86: think-lmi: Fix sysfs group cleanup platform/x86: think-lmi: Fix kobject cleanup platform/x86: think-lmi: Create ksets consecutively platform/mellanox: mlxreg-lc: Fix logic error in power state check i2c: Re-enable piix4 driver on non-x86 Move FCH header to a location accessible by all archs platform/x86/intel/hid: Add Wildcat Lake support platform/x86: dell-wmi-sysman: Fix class device unregistration platform/x86: think-lmi: Fix class device unregistration platform/x86: hp-bioscfg: Fix class device unregistration platform/x86: Update swnode graph for amd isp4 platform/x86: dell-wmi-sysman: Fix WMI data block retrieval in sysfs callbacks platform/x86: wmi: Update documentation of WCxx/WExx ACPI methods platform/x86: wmi: Fix WMI event enablement platform/mellanox: nvsw-sn2201: Fix bus number in adapter error message platform/mellanox: Fix spelling and comment clarity in Mellanox drivers platform/mellanox: mlxbf-pmc: Fix duplicate event ID for CACHE_DATA1 platform/x86: thinkpad_acpi: handle HKEY 0x1402 event platform/x86: asus-nb-wmi: add DMI quirk for ASUS Zenbook Duo UX8406CA platform/x86: dell-lis3lv02d: Add Latitude 5500 ...
…ernel/git/broonie/spi Pull spi fixes from Mark Brown: "As well as a few driver specific fixes we've got a core change here which raises the hard coded limit on the number of devices we can support on one SPI bus since some FPGA based systems are running into the existing limit. This is not a good solution but it's one suitable for this point in the release cycle, we should dynamically size the relevant data structures which I hope will happen in the next couple of merge windows. We also pull in a MTD fix for the Qualcomm SNAND driver, the two fixes cover the same issue and merging them together minimises bisection issues" * tag 'spi-fix-v6.16-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: spi: cadence-quadspi: fix cleanup of rx_chan on failure paths spi: spi-fsl-dspi: Clear completion counter before initiating transfer spi: Raise limit on number of chip selects to 24 mtd: nand: qpic_common: prevent out of bounds access of BAM arrays spi: spi-qpic-snand: reallocate BAM transactions
…inux/kernel/git/broonie/regulator Pull regulator fixes from Mark Brown: "A few driver fixes (the GPIO one being potentially nasty, though it has been there for a while without anyone reporting it), and one core fix for the rarely used combination of coupled regulators and unbinding" * tag 'regulator-fix-v6.16-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: regulator: gpio: Fix the out-of-bounds access to drvdata::gpiods regulator: mp886x: Fix ID table driver_data regulator: sy8824x: Fix ID table driver_data regulator: tps65219: Fix devm_kmalloc size allocation regulator: core: fix NULL dereference on unbind due to stale coupling data
