Subject: [PATCH for v3.18 00/18] Backport CVE-2017-13166 fixes to Kernel 3.18

Hi Greg,

Those are the backports meant to solve CVE-2017-13166 on Kernel 3.18.

It contains two v4l2-ctrls fixes that are required to avoid crashes
at the test application.

I wrote two patches myself for Kernel 3.18 in order to solve some
issues specific for Kernel 3.18 with aren't needed upstream.
one is actually a one-line change backport. The other one makes
sure that both 32-bits and 64-bits version of some ioctl calls
will return the same value for a reserved field.

I noticed an extra bug while testing it, but the bug also hits upstream,
and should be backported all the way down all stable/LTS versions.
So, I'll send it the usual way, after merging upsream.

Regards,
Mauro
