[GIT PULL] SCSI fixes for 6.0-rc2

From: James Bottomley
Date: Fri Oct 28 2022 - 17:16:17 EST

21 small fixes, all in drivers. Some of these arrived during the merge
window and got held over to make sure of testing on the -rc tree. The
biggest change is for Standards conformance in the target driver,
closely followed by a set of bug fixes in megaraid_sas.

The patch is available here:

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

The short changelog is:

Christoph Hellwig (1):
scsi: target: iblock: Fold iblock_emulate_read_cap_with_block_size() into iblock_get_blocks()

Manish Rangankar (1):
scsi: qla2xxx: Use transport-defined speed mask for supported_speeds

Markus Fuchs (1):
scsi: ufs: core: Remove unneeded casts from void *

Michal Kubecek (1):
scsi: mpi3mr: Select CONFIG_SCSI_SAS_ATTRS

Rafael Mendonca (1):
