[PATCH] video: fbdev: atmel: fix warning for const return value

From: Rob Herring
Date: Mon Jul 27 2015 - 11:41:52 EST


A const on a return value is meaningless and generates a warning on some
versions of gcc:

drivers/video/fbdev/atmel_lcdfb.c:1003: warning: type qualifiers ignored on function return type

This was found on 0-day with avr32 builds with CONFIG_OF enabled, but
it doesn't seem to generate warnings for other arches.
