From 656d4f332c02b14e62fe3f4247a1dcdc33961de6 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 15 Aug 2012 18:10:03 +0200 Subject: fbdev: sh_mobile_lcdc: Store the backlight brightness internally There's no need to query the hardware for the currenty brightness value through a platform data callback when we can cache the value internally in the LCDC driver.
