Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull more SCSI updates from James Bottomley: "Mostly small bug fixes and trivial updates. The major new core update is a change to the way device, target and host reference counting is done to try to make it more robust (this change has soaked for a while to try to winkle out any bugs)" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: pm8001: Fix typo 'the the' in comment scsi: megaraid_sas: Remove redundant variable cmd_type scsi: FlashPoint: Remove redundant variable bm_int_st scsi: zfcp: Fix missing auto port scan and thus missing target ports scsi: core: Call blk_mq_free_tag_set() earlier scsi: core: Simplify LLD module reference counting scsi: core: Make sure that hosts outlive targets scsi: core: Make sure that targets outlive devices scsi: ufs: ufs-pci: Correct check for RESET DSM scsi: target: core: De-RCU of se_lun and se_lun acl scsi: target: core: Fix race during ACL removal scsi: ufs: core: Correct ufshcd_shutdown() flow scsi: ufs: core: Increase the maximum data buffer size scsi: lpfc: Check the return value of alloc_workqueue()
