Pull SCSI fixes from James Bottomley:
 "Two small fixes, both in upper layer drivers (scsi disk and cdrom).

  The sd one is fixing a commit changing revalidation that came from the
  block tree a while ago (5.10) and the sr one adds handling of a
  condition we didn't previously handle for manually removed media"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: sd: Call sd_revalidate_disk() for ioctl(BLKRRPART)
  scsi: sr: Return appropriate error code when disk is ejected
