3.5.7.21 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@oracle.com>

commit 909bd5926d474e275599094acad986af79671ac9 upstream.

We want the data stored in "addr" and "qual", but the extra ampersands
mean we are copying stack data instead.
