Subject[PATCH 3.2 84/87] aacraid: missing capable() check in compat ioctl
3.2.53-rc1 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.
