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, libsas). The major core change is a rework to remove the two helpers around scsi_execute_cmd and use it as the only submission interface along with other minor fixes and updates" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (142 commits) scsi: ufs: core: Fix an error handling path in ufshcd_read_desc_param() scsi: ufs: core: Fix device management cmd timeout flow scsi: aic94xx: Add missing check for dma_map_single() scsi: smartpqi: Replace one-element array with flexible-array member scsi: mpt3sas: Fix a memory leak scsi: qla2xxx: Remove the unused variable wwn scsi: ufs: core: Fix kernel-doc syntax scsi: ufs: core: Add hibernation callbacks scsi: snic: Fix memory leak with using debugfs_lookup() scsi: ufs: core: Limit DMA alignment check scsi: Documentation: Correct spelling scsi: Documentation: Correct spelling scsi: target: Documentation: Correct spelling scsi: aacraid: Allocate cmd_priv with scsicmd scsi: ufs: qcom: dt-bindings: Add SM8550 compatible string scsi: ufs: ufs-qcom: Clear qunipro_g4_sel for HW version major 5 scsi: ufs: qcom: fix platform_msi_domain_free_irqs() reference scsi: ufs: core: Enable DMA clustering scsi: ufs: exynos: Fix the maximum segment size scsi: ufs: exynos: Fix DMA alignment for PAGE_SIZE != 4096 ...
