Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley: "This update includes the usual round of major driver updates (ncr5380, ufs, lpfc, be2iscsi, hisi_sas, storvsc, cxlflash, aacraid, megaraid_sas, ...). There's also an assortment of minor fixes and the major update of switching a bunch of drivers to pci_alloc_irq_vectors from Christoph" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (188 commits) scsi: megaraid_sas: handle dma_addr_t right on 32-bit scsi: megaraid_sas: array overflow in megasas_dump_frame() scsi: snic: switch to pci_irq_alloc_vectors scsi: megaraid_sas: driver version upgrade scsi: megaraid_sas: Change RAID_1_10_RMW_CMDS to RAID_1_PEER_CMDS and set value to 2 scsi: megaraid_sas: Indentation and smatch warning fixes scsi: megaraid_sas: Cleanup VD_EXT_DEBUG and SPAN_DEBUG related debug prints scsi: megaraid_sas: Increase internal command pool scsi: megaraid_sas: Use synchronize_irq to wait for IRQs to complete scsi: megaraid_sas: Bail out the driver load if ld_list_query fails scsi: megaraid_sas: Change build_mpt_mfi_pass_thru to return void scsi: megaraid_sas: During OCR, if get_ctrl_info fails do not continue with OCR scsi: megaraid_sas: Do not set fp_possible if TM capable for non-RW syspdIO, change fp_possible to bool scsi: megaraid_sas: Remove unused pd_index from megasas_build_ld_nonrw_fusion scsi: megaraid_sas: megasas_return_cmd does not memset IO frame to zero scsi: megaraid_sas: max_fw_cmds are decremented twice, remove duplicate scsi: megaraid_sas: update can_queue only if the new value is less scsi: megaraid_sas: Change max_cmd from u32 to u16 in all functions scsi: megaraid_sas: set pd_after_lb from MR_BuildRaidContext and initialize pDevHandle to MR_DEVHANDLE_INVALID scsi: megaraid_sas: latest controller OCR capability from FW before sending shutdown DCMD ...
