[GIT PULL] SCSI fixes for 6.3-rc5

From: James Bottomley
Date: Fri Apr 07 2023 - 17:42:18 EST


Four small fixes, all in drivers. They're all one or two lines except
for the ufs one, but that's a simple revert of a previous feature.

The patch is available here:

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

The short changelog is:

Adrien Thierry (1):
scsi: Revert "scsi: ufs: core: Initialize devfreq synchronously"

Li Zetao (1):
scsi: qla2xxx: Fix memory leak in qla2x00_probe_one()

Ranjan Kumar (1):
scsi: mpi3mr: Handle soft reset in progress fault code (0xF002)

Zhong Jinghua (1):
scsi: iscsi_tcp: Check that sock is valid before iscsi_set_param()
