3.16.61-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 18c9a99bce2a57dfd7e881658703b5d7469cc7b9 upstream.
We read from the cdb[] buffer in ata_exec_internal_sg(). It has to be
ATAPI_CDB_LEN (16) bytes long, but this buffer is only 12 bytes.
Fixes: 213342053db5 ("libata: handle power transition of ODD")
