Subject: [PATCH 3.16 136/212] MIPS: BCM47XX: Fix button inversion for Asus
 WL-500W

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

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

From: Mirko Parthey <mirko.parthey@....de>

commit bdfdaf1a016ef09cb941f2edad485a713510b8d5 upstream.

The Asus WL-500W buttons are active high, but the software treats them
as active low. Fix the inverted logic.
