In ufshcd_host_reset_and_restore(), scale up clocks only when clock scaling is supported. Without this change CPU latency is voted for 0 (ufshcd_pm_qos_update) during resume unconditionally.

When both the RHBA and RPA FDMI requests time out, fnic reuses a frame to send ABTS for each of them. On send completion, this causes an attempt to free the same frame twice that leads to a crash. Fix crash by allocating separate frames for RHBA and RPA, and modify ABTS logic accordingly. Tested by checking MDS for FDMI information. Tested by using instrumented driver to: - Drop PLOGI response - Drop RHBA response - Drop RPA response - Drop RHBA and RPA response - Drop PLOGI response + ABTS response - Drop RHBA response + ABTS response - Drop RPA response + ABTS response - Drop RHBA and RPA response + ABTS response for both of them Fixes: 09c1e6a ("scsi: fnic: Add and integrate support for FDMI") Reviewed-by: Sesidhar Baddela <[email protected]> Reviewed-by: Arulprabhu Ponnusamy <[email protected]> Reviewed-by: Gian Carlo Boffa <[email protected]> Tested-by: Arun Easi <[email protected]> Co-developed-by: Arun Easi <[email protected]> Signed-off-by: Arun Easi <[email protected]> Tested-by: Karan Tilak Kumar <[email protected]> Cc: [email protected] Signed-off-by: Karan Tilak Kumar <[email protected]> Link: https://lore.kernel.org/r/[email protected] Reviewed-by: John Meneghini <[email protected]> Signed-off-by: Martin K.
