Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley: "Updates to the usual drivers (ufs, qla2xx, target, lpfc, smartpqi, mpi3mr). The main driver change that might cause issues on down the road is the conversion of some of our oldest surviving drivers to the DMA API (should only affect m68k). The only major core change is the rework of async resume; the rest are either completely trivial or for updating deprecated APIs" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (195 commits) scsi: target: Remove XDWRITEREAD emulated support scsi: megaraid: Remove the static variable initialisation scsi: ch: Do not initialise statics to 0 scsi: ufs: core: Fix spelling mistake "Cannnot" -> "Cannot" scsi: target: iscsi: Do not require target authentication scsi: target: iscsi: Allow AuthMethod=None scsi: target: iscsi: Support base64 in CHAP scsi: target: iscsi: Add support for extended CDB AHS scsi: ufs: dt-bindings: Add SC8280XP binding scsi: target: iscsi: Fix clang -Wformat warnings scsi: ufs: core: Read device property for ref clock scsi: libsas: Resume SAS host for phy reset or enable via sysfs scsi: hisi_sas: Modify v3 HW SATA completion error processing scsi: hisi_sas: Relocate DMA unmap of SMP task scsi: hisi_sas: Remove unnecessary variable to hold DMA map elements scsi: hisi_sas: Call hisi_sas_slave_configure() from slave_configure_v3_hw() scsi: mpi3mr: Delete a stray tab scsi: mpi3mr: Unlock on error path scsi: mpi3mr: Reduce VD queue depth on detecting throttling scsi: mpi3mr: Resource Based Metering ...
