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, lpfc, qla2xxx, mpi3mr, libsas). The major update (which causes a conflict with block, see below) is Christoph removing the queue limits and their associated block helpers. The remaining patches are assorted minor fixes and deprecated function updates plus a bit of constification" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (141 commits) scsi: mpi3mr: Sanitise num_phys scsi: lpfc: Copyright updates for 14.4.0.2 patches scsi: lpfc: Update lpfc version to 14.4.0.2 scsi: lpfc: Add support for 32 byte CDBs scsi: lpfc: Change lpfc_hba hba_flag member into a bitmask scsi: lpfc: Introduce rrq_list_lock to protect active_rrq_list scsi: lpfc: Clear deferred RSCN processing flag when driver is unloading scsi: lpfc: Update logging of protection type for T10 DIF I/O scsi: lpfc: Change default logging level for unsolicited CT MIB commands scsi: target: Remove unused list 'device_list' scsi: iscsi: Remove unused list 'connlist_err' scsi: ufs: exynos: Add support for Tensor gs101 SoC scsi: ufs: exynos: Add some pa_dbg_ register offsets into drvdata scsi: ufs: exynos: Allow max frequencies up to 267Mhz scsi: ufs: exynos: Add EXYNOS_UFS_OPT_TIMER_TICK_SELECT option scsi: ufs: exynos: Add EXYNOS_UFS_OPT_UFSPR_SECURE option scsi: ufs: dt-bindings: exynos: Add gs101 compatible scsi: qla2xxx: Fix debugfs output for fw_resource_count scsi: qedf: Ensure the copied buf is NUL terminated scsi: bfa: Ensure the copied buf is NUL terminated ...
