Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley: "This series is slightly unusual because it includes Arnd's compat ioctl tree here: 1c46a2cf2dbd Merge tag 'block-ioctl-cleanup-5.6' into 5.6/scsi-queue Excluding Arnd's changes, this is mostly an update of the usual drivers: megaraid_sas, mpt3sas, qla2xxx, ufs, lpfc, hisi_sas. There are a couple of core and base updates around error propagation and atomicity in the attribute container base we use for the SCSI transport classes. The rest is minor changes and updates" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (149 commits) scsi: hisi_sas: Rename hisi_sas_cq.pci_irq_mask scsi: hisi_sas: Add prints for v3 hw interrupt converge and automatic affinity scsi: hisi_sas: Modify the file permissions of trigger_dump to write only scsi: hisi_sas: Replace magic number when handle channel interrupt scsi: hisi_sas: replace spin_lock_irqsave/spin_unlock_restore with spin_lock/spin_unlock scsi: hisi_sas: use threaded irq to process CQ interrupts scsi: ufs: Use UFS device indicated maximum LU number scsi: ufs: Add max_lu_supported in struct ufs_dev_info scsi: ufs: Delete is_init_prefetch from struct ufs_hba scsi: ufs: Inline two functions into their callers scsi: ufs: Move ufshcd_get_max_pwr_mode() to ufshcd_device_params_init() scsi: ufs: Split ufshcd_probe_hba() based on its called flow scsi: ufs: Delete struct ufs_dev_desc scsi: ufs: Fix ufshcd_probe_hba() reture value in case ufshcd_scsi_add_wlus() fails scsi: ufs-mediatek: enable low-power mode for hibern8 state scsi: ufs: export some functions for vendor usage scsi: ufs-mediatek: add dbg_register_dump implementation scsi: qla2xxx: Fix a NULL pointer dereference in an error path scsi: qla1280: Make checking for 64bit support consistent scsi: megaraid_sas: Update driver version to 07.713.01.00-rc1 ...
