Message-ID: <1359526755-21145-1-git-send-email-acourbot@nvidia.com> Date: Wed, 30 Jan 2013 15:19:15 +0900 From: Alexandre Courbot <acourbot@...dia.com> To: Thierry Reding <thierry.reding@...onic-design.de>, Richard Purdie <rpurdie@...ys.net> CC: <linux-kernel@...r.kernel.org>, <linux-fbdev@...r.kernel.org>, <gnurou@...il.com>, Alexandre Courbot <acourbot@...dia.com> 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.
