Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull more SCSI updates from James Bottomley: "The set of core changes here is Christoph's submission path cleanups. These introduced a couple of regressions when first proposed so they got held over from the initial merge window pull request to give more testing time, which they've now had and Syzbot has confirmed the regression it detected is fixed. The other main changes are two driver updates (arcmsr, pm80xx) and assorted minor clean ups" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (38 commits) scsi: qla2xxx: Fix return of uninitialized value in rval scsi: core: Set sc_data_direction to DMA_NONE for no-transfer commands scsi: sr: Initialize ->cmd_len scsi: arcmsr: Update driver version to v1.50.00.02-20200819 scsi: arcmsr: Add support for ARC-1886 series RAID controllers scsi: arcmsr: Fix device hot-plug monitoring timer stop scsi: arcmsr: Remove unnecessary syntax scsi: pm80xx: Driver version update scsi: pm80xx: Increase the number of outstanding I/O supported to 1024 scsi: pm80xx: Remove DMA memory allocation for ccb and device structures scsi: pm80xx: Increase number of supported queues scsi: sym53c8xx_2: Fix sizeof() mismatch scsi: isci: Fix a typo in a comment scsi: qla4xxx: Fix inconsistent format argument type scsi: myrb: Fix inconsistent format argument types scsi: myrb: Remove redundant assignment to variable timeout scsi: bfa: Fix error return in bfad_pci_init() scsi: fcoe: Simplify the return expression of fcoe_sysfs_setup() scsi: snic: Simplify the return expression of svnic_cq_alloc() scsi: fnic: Simplify the return expression of vnic_wq_copy_alloc() ...
