3.2.85-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit c88e739b1fad662240e99ecbd0bdaac871717987 upstream.
These structs have holes and reserved struct members which aren't
cleared. I've added a memset() so we don't leak stack information.
