Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull first round of SCSI updates from James Bottomley:
"This includes driver updates from the usual suspects (bfa, arcmsr,
scsi_dh_alua, lpfc, storvsc, cxlflash).
The major change is the addition of the hisi_sas driver, which is an
ARM platform device for SAS. The other change of note is an enormous
style transformation to the atp870u driver (which is our worst written
SCSI driver)"
* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (169 commits)
cxlflash: Enable device id for future IBM CXL adapter
cxlflash: Resolve oops in wait_port_offline
cxlflash: Fix to resolve cmd leak after host reset
cxlflash: Removed driver date print
cxlflash: Fix to avoid virtual LUN failover failure
cxlflash: Fix to escalate LINK_RESET also on port 1
storvsc: Tighten up the interrupt path
storvsc: Refactor the code in storvsc_channel_init()
storvsc: Properly support Fibre Channel devices
storvsc: Fix a bug in the layout of the hv_fc_wwn_packet
mvsas: Add SGPIO support to Marvell 94xx
mpt3sas: A correction in unmap_resources
hpsa: Add box and bay information for enclosure devices
hpsa: Change SAS transport devices to bus 0.
hpsa: fix path_info_show
cciss: print max outstanding commands as a hex value
scsi_debug: Increase the reported optimal transfer length
lpfc: Update version to 11.0.0.10 for upstream patch set
lpfc: Use kzalloc instead of kmalloc
lpfc: Delete unnecessary checks before the function call "mempool_destroy"
