Merge tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley: "This patch consists of the usual driver updates (qla2xxx, qla4xxx, lpfc, be2iscsi, fnic, ufs, NCR5380) The NCR5380 is the addition to maintained status of a long neglected driver for older hardware. In addition there are a lot of minor fixes and cleanups and some more updates to make scsi mq ready" * tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (130 commits) include/scsi/osd_protocol.h: remove unnecessary __constant mvsas: Recognise device/subsystem 9485/9485 as 88SE9485 Revert "be2iscsi: Fix processing cqe for cxn whose endpoint is freed" mptfusion: fix msgContext in mptctl_hp_hostinfo acornscsi: remove linked command support scsi/NCR5380: dprintk macro fusion: Remove use of DEF_SCSI_QCMD fusion: Add free msg frames to the head, not tail of list mpt2sas: Add free smids to the head, not tail of list mpt2sas: Remove use of DEF_SCSI_QCMD mpt2sas: Remove uses of serial_number mpt3sas: Remove use of DEF_SCSI_QCMD mpt3sas: Remove uses of serial_number qla2xxx: Use kmemdup instead of kmalloc + memcpy qla4xxx: Use kmemdup instead of kmalloc + memcpy qla2xxx: fix incorrect debug printk be2iscsi: Bump the driver version be2iscsi: Fix processing cqe for cxn whose endpoint is freed be2iscsi: Fix destroy MCC-CQ before MCC-EQ is destroyed be2iscsi: Fix memory corruption in MBX path ...
