Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley: "Five small fixes. Some of these, like the nested spinlock overwriting saved flags and the Kasan use after free look serious, but they seem not to have been picked up in testing or seen in the field. The biggest user visible issue is probably the wrong device handler for Clariion, which means that alua doesn't bind to the array like it should" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: ipr: Fix async error WARN_ON scsi: zfcp: spin_lock_irqsave() is not nestable scsi: Remove one useless stack variable scsi: Fix use-after-free scsi: Replace wrong device handler name for CLARiiON arrays
