Subject: Re: [RFC][PATCH V2 2/3] pwm_backlight: use power sequences

Sorry, I just noticed a mistake in this patch I made while merging 
another one. The following also needs to be changed, otherwise the 
power-on sequence will never be executed:

diff --git a/drivers/video/backlight/pwm_bl.c 
b/drivers/video/backlight/pwm_bl.c
index 1a38953..4546d23 100644
--- a/drivers/video/backlight/pwm_bl.c
+++ b/drivers/video/backlight/pwm_bl.c
@@ -65,7 +98,7 @@ static int pwm_backlight_update_status(struct 
backlight_device *bl)
                 duty_cycle = pb->lth_brightness +
                      (duty_cycle * (pb->period - pb->lth_brightness) / 
max);
                 pwm_config(pb->pwm, duty_cycle, pb->period);
-               pwm_enable(pb->pwm);
+               pwm_backlight_on(bl);
         }


Apologies for the inconvenience.

Alex.
