From 0132267d659107616eb044777f1b0be55381129a Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Wed, 30 Jan 2013 15:19:15 +0900 Subject: [PATCH] pwm-backlight: handle BL_CORE_FBBLANK state According to include/linux/backlight.h, the fb_blank field is to be removed and blank status should preferably be set by setting the BL_CORE_FBBLANK bit of the state field. This patch ensures this condition is also taken into account when updating the backlight state.
