Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"Two iscsi fixes.
One for an oops in the client which can be triggered by the server
authentication protocol and the other in the target code which causes
data corruption"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: iscsi: set auth_protocol back to NULL if CHAP_A value is not supported
scsi: target/iblock: Fix overrun in WRITE SAME emulation
