Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley: "The usual driver updates (ufs, qla2xxx, tcmu, ibmvfc, lpfc, smartpqi, hisi_sas, qedi, qedf, mpt3sas) and minor bug fixes. There are only three core changes: adding sense codes, cleaning up noretry and adding an option for limitless retries" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (226 commits) scsi: hisi_sas: Recover PHY state according to the status before reset scsi: hisi_sas: Filter out new PHY up events during suspend scsi: hisi_sas: Add device link between SCSI devices and hisi_hba scsi: hisi_sas: Add check for methods _PS0 and _PR0 scsi: hisi_sas: Add controller runtime PM support for v3 hw scsi: hisi_sas: Switch to new framework to support suspend and resume scsi: hisi_sas: Use hisi_hba->cq_nvecs for calling calling synchronize_irq() scsi: qedf: Remove redundant assignment to variable 'rc' scsi: lpfc: Remove unneeded variable 'status' in lpfc_fcp_cpu_map_store() scsi: snic: Convert to use DEFINE_SEQ_ATTRIBUTE macro scsi: qla4xxx: Delete unneeded variable 'status' in qla4xxx_process_ddb_changed scsi: sun_esp: Use module_platform_driver to simplify the code scsi: sun3x_esp: Use module_platform_driver to simplify the code scsi: sni_53c710: Use module_platform_driver to simplify the code scsi: qlogicpti: Use module_platform_driver to simplify the code scsi: mac_esp: Use module_platform_driver to simplify the code scsi: jazz_esp: Use module_platform_driver to simplify the code scsi: mvumi: Fix error return in mvumi_io_attach() scsi: lpfc: Drop nodelist reference on error in lpfc_gen_req() scsi: be2iscsi: Fix a theoretical leak in beiscsi_create_eqs() ...
