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@xxxxxxxxx> -- 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.
