3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@oracle.com>
commit f856567b930dfcdbc3323261bf77240ccdde01f5 upstream.
In commit d496f94d22d1 ('[SCSI] aacraid: fix security weakness') we added a check on CAP_SYS_RAWIO to the ioctl. The compat ioctls need the check as well.
