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 (scsi_debug, ufs, lpfc, st, fnic, mpi3mr, mpt3sas) and the removal of cxlflash. The only non-trivial core change is an addition to unit attention handling to recognize UAs for power on/reset and new media so the tape driver can use it" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (107 commits) scsi: st: Tighten the page format heuristics with MODE SELECT scsi: st: ERASE does not change tape location scsi: st: Fix array overflow in st_setup() scsi: target: tcm_loop: Fix wrong abort tag scsi: lpfc: Restore clearing of NLP_UNREG_INP in ndlp->nlp_flag scsi: hisi_sas: Fixed failure to issue vendor specific commands scsi: fnic: Remove unnecessary NUL-terminations scsi: fnic: Remove redundant flush_workqueue() calls scsi: core: Use a switch statement when attaching VPD pages scsi: ufs: renesas: Add initialization code for R-Car S4-8 ES1.2 scsi: ufs: renesas: Add reusable functions scsi: ufs: renesas: Refactor 0x10ad/0x10af PHY settings scsi: ufs: renesas: Remove register control helper function scsi: ufs: renesas: Add register read to remove save/set/restore scsi: ufs: renesas: Replace init data by init code scsi: ufs: dt-bindings: renesas,ufs: Add calibration data scsi: mpi3mr: Task Abort EH Support scsi: storvsc: Don't report the host packet status as the hv status scsi: isci: Make most module parameters static scsi: megaraid_sas: Make most module parameters static ...
