Subject: [PATCH 3.16.y-ckt 043/126] HID: add battery quirk for USB_DEVICE_ID_APPLE_ALU_WIRELESS_2011_ISO keyboard

3.16.7-ckt5 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Karl Relton <karllinuxtest.relton@...world.com>

commit da940db41dcf8c04166f711646df2f35376010aa upstream.

Apple bluetooth wireless keyboard (sold in UK) has always reported zero
for battery strength no matter what condition the batteries are actually
in. With this patch applied (applying same quirk as other Apple
keyboards), the battery strength is now correctly reported.
