Maybe we can just add his name in parenthesis. Would this patch description be
ok for you, Andrew and Alan?

Fix VIDIOCGAP corruption in ivtv

From: Alan Cox <alan@xxxxxxxxxx>

Frank Bennett reported that ivtv was causing skype to crash. With help
from one of their developers (Andrew Macks) he showed it was a kernel problem.
VIDIOCGCAP copies a name into a fixed length buffer - ivtv uses names
that are too long and does not truncate them so corrupts a few bytes of
the app data area.

Possibly the names also want trimming but for now this should fix the
corruption case.
