Subject[GIT PULL] SCSI fixes for 5.3-rc2
From
Date
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 minor fixes.

The patch is available here:

git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes

The short changelog is:

Don Brace (2):
scsi: hpsa: remove printing internal cdb on tag collision
scsi: hpsa: correct scsi command status issue after reset

Hannes Reinecke (3):
scsi: fcoe: pass in fcoe_rport structure instead of fc_rport_priv
scsi: fcoe: Embed fc_rport_priv in fcoe_rport structure
scsi: libfc: Whitespace cleanup in libfc.h

Jia-Ju Bai (1):
scsi: qla2xxx: Fix possible fcport null-pointer dereferences

Suganath Prabu (1):
scsi: mpt3sas: Use 63-bit DMA addressing on SAS35 HBA

And the diffstat:
