3.16.48-rc1 review patch. If anyone has any objections, please let me know.

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
commit ed9ab4287f96e66340e0390e2c583f2f9110cba0 upstream.
Quirking the following AMI USB device with ALWAYS_POLL fixes an AMI
virtual keyboard and mouse from not responding and timing out when
it is attached to a ppc64el Power 8 system and when we have some
rapid open/closes on the mouse device.
