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 one new driver: cxlflash plus the usual grab bag of updates for the major drivers: qla2xxx, ipr, storvsc, pm80xx, hptiop, plus a few assorted fixes. There's another tranch coming, but I want to incubate it another few days in the checkers, plus it includes a mpt2sas separated lifetime fix, which Avago won't get done testing until Friday" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (85 commits) aic94xx: set an error code on failure storvsc: Set the error code correctly in failure conditions storvsc: Allow write_same when host is windows 10 storvsc: use storage protocol version to determine storage capabilities storvsc: use correct defaults for values determined by protocol negotiation storvsc: Untangle the storage protocol negotiation from the vmbus protocol negotiation. storvsc: Use a single value to track protocol versions storvsc: Rather than look for sets of specific protocol versions, make decisions based on ranges. cxlflash: Remove unused variable from queuecommand cxlflash: shift wrapping bug in afu_link_reset() cxlflash: off by one bug in cxlflash_show_port_status() cxlflash: Virtual LUN support cxlflash: Superpipe support cxlflash: Base error recovery support qla2xxx: Update driver version to 8.07.00.26-k qla2xxx: Add pci device id 0x2261. qla2xxx: Fix missing device login retries. qla2xxx: do not clear slot in outstanding cmd array qla2xxx: Remove decrement of sp reference count in abort handler. qla2xxx: Add support to show MPI and PEP FW version for ISP27xx. ...
