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
