From 5eb02c01bd1f3ef195989ab05e835e2b0711b5a9 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Thu, 21 Feb 2013 16:44:04 -0800 Subject: [PATCH] drivers/video/backlight/adp88?0_bl.c: fix resume Clearing the NSTBY bit in the control register also automatically clears the BLEN bit. So we need to make sure to set it again during resume, otherwise the backlight will stay off.
