Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley: "This series consists of the usual driver updates (ufs, ibmvfc, qla2xxx, hisi_sas, pm80xx) plus the removal of the gdth driver (which is bound to cause conflicts with a trivial change somewhere). The only big major rework of note is the one from Hannes trying to clean up our result handling code in the drivers to make it consistent" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (194 commits) scsi: MAINTAINERS: Adjust to reflect gdth scsi driver removal scsi: ufs: Give clk scaling min gear a value scsi: lpfc: Fix 'physical' typos scsi: megaraid_mbox: Fix spelling of 'allocated' scsi: qla2xxx: Simplify the calculation of variables scsi: message: fusion: Fix 'physical' typos scsi: target: core: Change ASCQ for residual write scsi: target: core: Signal WRITE residuals scsi: target: core: Set residuals for 4Kn devices scsi: hisi_sas: Add trace FIFO debugfs support scsi: hisi_sas: Flush workqueue in hisi_sas_v3_remove() scsi: hisi_sas: Enable debugfs support by default scsi: hisi_sas: Don't check .nr_hw_queues in hisi_sas_task_prep() scsi: hisi_sas: Remove deferred probe check in hisi_sas_v2_probe() scsi: lpfc: Add auto select on IRQ_POLL scsi: ncr53c8xx: Fix typos scsi: lpfc: Fix ancient double free scsi: qla2xxx: Fix some memory corruption scsi: qla2xxx: Remove redundant NULL check scsi: megaraid: Fix ifnullfree.cocci warnings ...

+ platform that doesn't support UFSHCD_CAP_CLK_SCALING, we can
+ disable/enable WriteBooster through this sysfs node.
