Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"Two small fixes to the mpi3mr driver. One to avoid oversize
allocations in tracing and the other to fix an uninitialized spinlock
in the user to driver feature request code (used to trigger dumps and
the like)"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: mpi3mr: Avoid MAX_PAGE_ORDER WARNING for buffer allocations
scsi: mpi3mr: Add missing spin_lock_init() for mrioc->trigger_lock
