Subject[GIT PULL] SCSI fixes for 5.11-rc3
From
Date
Nine minor fixes, 7 in drivers and 2 in the core SCSI disk driver (sd)
which should be harmless involving removing an unused variable and
quietening a spurious warning.

The patch is available here:

git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes

The short changelog is:

Can Guo (1):
scsi: ufs: Correct the LUN used in eh_device_reset_handler() callback

Colin Ian King (1):
scsi: mpt3sas: Fix spelling mistake in Kconfig "compatiblity" -> "compatibility"

Dinghao Liu (1):
scsi: scsi_debug: Fix memleak in scsi_debug_init()

Ewan D. Milne (1):
scsi: sd: Suppress spurious errors when WRITE SAME is being disabled

Kiwoong Kim (1):
scsi: ufs: Relocate flush of exceptional event

Lukas Bulwahn (1):
scsi: sd: Remove obsolete variable in sd_remove()

Nilesh Javali (1):
scsi: qedi: Correct max length of CHAP secret

Stanley Chu (2):
scsi: ufs: Relax the condition of UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL
scsi: ufs: Fix possible power drain during system suspend
