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

Pull SCSI fixes from James Bottomley:
 "Seven fixes to four drivers with no core changes.

  The mpt3sas one is theoretical until we get a CPU that goes up to 64
  bits physical, the qla2xxx one fixes an oops in a driver
  initialization error leg and the others are mostly cosmetic"

[ The fcoe patches may be worth highlighting - they may be "just"
  cleanups, but they simplify and fix the odd fc_rport_priv structure
  handling rules so that the new gcc-9 warnings about memset crossing
  structure boundaries are gone.

  The old code was hard for humans to understand too, and really
  confused the compiler sanity checks  - Linus ]

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: qla2xxx: Fix possible fcport null-pointer dereferences
  scsi: mpt3sas: Use 63-bit DMA addressing on SAS35 HBA
  scsi: hpsa: remove printing internal cdb on tag collision
  scsi: hpsa: correct scsi command status issue after reset
  scsi: fcoe: pass in fcoe_rport structure instead of fc_rport_priv
  scsi: fcoe: Embed fc_rport_priv in fcoe_rport structure
