Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley: "This is mostly updates of the usual driver suspects: arcmsr, scsi_debug, mpt3sas, lpfc, cxlflash, qla2xxx, aacraid, megaraid_sas, hisi_sas. We also have a rework of the libsas hotplug handling to make it more robust, a slew of 32 bit time conversions and fixes, and a host of the usual minor updates and style changes. The biggest potential for regressions is the libsas hotplug changes, but so far they seem stable under testing" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (313 commits) scsi: qla2xxx: Fix logo flag for qlt_free_session_done() scsi: arcmsr: avoid do_gettimeofday scsi: core: Add VENDOR_SPECIFIC sense code definitions scsi: qedi: Drop cqe response during connection recovery scsi: fas216: fix sense buffer initialization scsi: ibmvfc: Remove unneeded semicolons scsi: hisi_sas: fix a bug in hisi_sas_dev_gone() scsi: hisi_sas: directly attached disk LED feature for v2 hw scsi: hisi_sas: devicetree: bindings: add LED feature for v2 hw scsi: megaraid_sas: NVMe passthrough command support scsi: megaraid: use ktime_get_real for firmware time scsi: fnic: use 64-bit timestamps scsi: qedf: Fix error return code in __qedf_probe() scsi: devinfo: fix format of the device list scsi: qla2xxx: Update driver version to 10.00.00.05-k scsi: qla2xxx: Add XCB counters to debugfs scsi: qla2xxx: Fix queue ID for async abort with Multiqueue scsi: qla2xxx: Fix warning for code intentation in __qla24xx_handle_gpdb_event() scsi: qla2xxx: Fix warning during port_name debug print scsi: qla2xxx: Fix warning in qla2x00_async_iocb_timeout() ...
