tools/testing/selftests/x86/Makefile	Add sigtrap_loop to the list of test targets

fs/jffs2/summary.c:860

• At the out label the code calls spin_lock(&c->erase_completion_lock) and then returns without ever releasing the lock, leading to a deadlock. It should call spin_unlock(&c->erase_completion_lock) before returning.

	jeb = c->nextblock;

net/nfc/nci/uart.c:121

• Removing the early assignment to tty->disc_data means it may remain uninitialized on error paths. Initialize tty->disc_data = NULL before nu->ops.open and explicitly clear it on all failure branches.

	nu->tty = tty;
