Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley: "Two simple fixes in the upper drivers (so both fairly core), one in enclosures, which fixes replugging a device into an enclosure slot and one in the disk driver which fixes revalidating a drive with protection information (PI) to make it a non-PI drive ... previously we were still remembering the old PI state. Both fixed issues are quite rare in the field" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: enclosure: Fix stale device oops with hot replug scsi: sd: Clear sdkp->protection_type if disk is reformatted without PI
