From: Andrzej Hajda Date: Fri, 30 May 2014 10:10:49 +0000 (+0200) Subject: backlight: Show brightness even if get_brightness is not implemented X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b3de3402e5ab8edfbbdbbb86393692431522f6d3;p=linux-beck.git backlight: Show brightness even if get_brightness is not implemented Many implementations of get_brightness operation returns only value of props.brightness field. This change makes such implementations unnecessary.
