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, pm80xx, lpfc, mpi3mr, mpt3sas, hisi_sas, libsas) and minor updates and bug fixes. The most impactful change is likely the switch from GFP_DMA to GFP_KERNEL in a bunch of drivers, but even that shouldn't affect too many people" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (121 commits) scsi: mpi3mr: Bump driver version to 8.0.0.61.0 scsi: mpi3mr: Fixes around reply request queues scsi: mpi3mr: Enhanced Task Management Support Reply handling scsi: mpi3mr: Use TM response codes from MPI3 headers scsi: mpi3mr: Add io_uring interface support in I/O-polled mode scsi: mpi3mr: Print cable mngnt and temp threshold events scsi: mpi3mr: Support Prepare for Reset event scsi: mpi3mr: Add Event acknowledgment logic scsi: mpi3mr: Gracefully handle online FW update operation scsi: mpi3mr: Detect async reset that occurred in firmware scsi: mpi3mr: Add IOC reinit function scsi: mpi3mr: Handle offline FW activation in graceful manner scsi: mpi3mr: Code refactor of IOC init - part2 scsi: mpi3mr: Code refactor of IOC init - part1 scsi: mpi3mr: Fault IOC when internal command gets timeout scsi: mpi3mr: Display IOC firmware package version scsi: mpi3mr: Handle unaligned PLL in unmap cmnds scsi: mpi3mr: Increase internal cmnds timeout to 60s scsi: mpi3mr: Do access status validation before adding devices scsi: mpi3mr: Add support for PCIe Managed Switch SES device ...
