Fully half this pull is updates to lpfc and qla2xxx which got committed just as the merge window opened. A sizeable fraction of the driver updates are simple bug fixes (and lock reworks for bug fixes in the case of lpfc), so rather than splitting the few actual enhancements out, we're just adding the drivers to the -rc1 pull. The enhancements for lpfc are log message removals, copyright updates and three patches redefining types. For qla2xxx it's just removing a debug message on module removal and the manufacturer detail update. The two major fixes are the sg teardown race and a core error leg problem with the procfs directory not being removed if we destroy a created host that never got to the running state. The rest are minor fixes and constifications. The patch is available here: git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes The short changelog is: Alexander Wetzel (1): scsi: sg: Avoid sg device teardown race Bikash Hazarika (1): scsi: qla2xxx: Update manufacturer detail Colin Ian King (1): scsi: target: iscsi: Remove unused variable xfer_len Damien Le Moal (1): scsi: sd: Fix TCG OPAL unlock on system resume Dmitry Baryshkov (1): scsi: ufs: qcom: Provide default cycles_in_1us value Guilherme G.
