Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley: "This is a set of SAS and SATA fixes; there are one or two longstanding bug fixes, but most of this is regression fixes." * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: [SCSI] libfc: update mfs boundry checking [SCSI] Revert "[SCSI] libsas: fix sas port naming" [SCSI] libsas: fix false positive 'device attached' conditions [SCSI] libsas, libata: fix start of life for a sas ata_port [SCSI] libsas: fix ata_eh clobbering ex_phys via smp_ata_check_ready [SCSI] libsas: unify domain_device sas_rphy lifetimes [SCSI] libsas: fix sas_get_port_device regression [SCSI] libsas: fix sas_find_bcast_phy() in the presence of 'vacant' phys [SCSI] libsas: introduce sas_work to fix sas_drain_work vs sas_queue_work [SCSI] libata: Pass correct DMA device to scsi host [SCSI] scsi_lib: use correct DMA device in __scsi_alloc_queue
