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

Pull SCSI fixes from James Bottomley:
 "Thirteen small fixes: The hopefully final effort to get the lpfc nvme
  kconfig problems sorted, there's one important sg fix (user can induce
  read after end of buffer) and one minor enhancement (adding an extra
  PCI ID to qedi). The rest are a set of minor fixes, which mostly occur
  as user visible in error legs or on specific devices"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: ufs: remove the duplicated checking for supporting clkscaling
  scsi: lpfc: fix building without debugfs support
  scsi: lpfc: Fix PT2PT PRLI reject
  scsi: hpsa: fix volume offline state
  scsi: libsas: fix ata xfer length
  scsi: scsi_dh_alua: Warn if the first argument of alua_rtpg_queue() is NULL
  scsi: scsi_dh_alua: Ensure that alua_activate() calls the completion function
  scsi: scsi_dh_alua: Check scsi_device_get() return value
  scsi: sg: check length passed to SG_NEXT_CMD_LEN
  scsi: ufshcd-platform: remove the useless cast in ERR_PTR/IS_ERR
  scsi: qedi: Add PCI device-ID for QL41xxx adapters.
  scsi: aacraid: Fix potential null access
  scsi: qla2xxx: Fix crash in qla2xxx_eh_abort on bad ptr
