Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI fixes from James Bottomley:
 "A set of seven fixes:

  Two regressions in the new hisi_sas arm driver, a blacklist entry for
  the marvell console which was causing a reset cascade without it, a
  race fix in the WRITE_SAME/DISCARD routines, a retry fix for the rdac
  driver, without which, it would prematurely return EIO and a couple of
  fixes for the hyper-v storvsc driver"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  block/sd: Return -EREMOTEIO when WRITE SAME and DISCARD are disabled
  SCSI: Add Marvell Console to VPD blacklist
  scsi_dh_rdac: always retry MODE SELECT on command lock violation
  storvsc: Use the specified target ID in device lookup
  storvsc: Install the storvsc specific timeout handler for FC devices
  hisi_sas: fix v1 hw check for slot error
  hisi_sas: add dependency for HAS_IOMEM
