U_xf86-fix-flush-input-to-work-with-Linux-evdev-device.patch
* So when we VT switch back and attempt to flush the input
devices, we don't succeed because evdev won't return part
of an event, since we were only asking for 4 bytes, we'd
only get -EINVAL back. This could later cause events to be
flushed that we shouldn't have gotten.
This is a fix for CVE-2013-1940. (bnc#814653)
