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

Pull SCSI fixes from James Bottomley:
 "This is three bug fixes: An fnic warning caused by sleeping under a
  lock, a major regression with our updated WRITE SAME/UNMAP logic which
  caused tons of USB devices (and one RAID card) to cease to function
  and a megaraid_sas firmware initialisation problem which causes kdump
  failures"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  [SCSI] Don't attempt to send extended INQUIRY command if skip_vpd_pages is set
  [SCSI] fnic: BUG: sleeping function called from invalid context during probe
  [SCSI] megaraid_sas: megaraid_sas driver init fails in kdump kernel
