Comment 2 Jeff Mahoney 2013-09-12 20:33:48 UTC

I"m afraid this isn't a driver we modify at all and it's in an area that we
haven't assembled a lot of expertise. You're going to need to file a report at
bugzilla.kernel.org instead. If there's a successful resolution, let us know
and we'll gladly include the fix.
