Date: Sun, 23 Dec 2012 18:21:18 +0100 From: Roland Stigge <stigge@...com.de> To: gregkh@...uxfoundation.org, corentin.chary@...il.com, mjg@...hat.com, platform-driver-x86@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Roland Stigge <stigge@...com.de> Subject: [PATCH] samsung-laptop: Set keyboard backlight initially After boot, /sys/devices/platform/samsung/leds/samsung::kbd_backlight/brightness shows the maximum value (8) by readout, but the led is off. I need to manually set it to the respective value to have keyboard backlight. Fixing via readout-write in samsung_leds_init(). Tested on Samsung NP900X3C. Signed-off-by: Roland Stigge <stigge@...com.de> -- I'm encountering a similar issue after suspend/resume (led is off). Still wondering if and by which technique I should add a respective .resume() because the driver currently doesn't have pm support and also doesn't register as a driver. Any hint appreciated.
