Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"Three fixes. One is the qla24xx MSI regression, one is a theoretical
problem over blacklist matching, which would bite USB badly if it ever
triggered and one is a system hang with a particular type of IPR
device"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
qla2xxx: Fix NULL pointer deref in QLA interrupt
SCSI: fix new bug in scsi_dev_info_list string matching
ipr: Clear interrupt on croc/crocodile when running with LSI
