Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"A single fix for libata: older devices don't support command duration
limits (CDL) and some don't support report opcodes, meaning there's no
way to tell if they support the command or not.
Reduce the problems of incorrectly using CDL commands on older devices
by checking SCSI spec compliance at SPC-5 (the spec which introduced
the command) before turning on CDL"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: core: ata: Do no try to probe for CDL on old drives
