Hi YH,

In the case of the panel disabled by the bootloader,
your patch still has the following code and always enables the backlight
in the probe function.
pb->enable_gpio = devm_gpiod_get_optional(&pdev->dev, "enable",
-						  GPIOD_OUT_HIGH);

You are right.

What do you think if I remove these two lines in my patch?
if (pb->enable_gpio)
	gpiod_direction_output(pb->enable_gpio, 0);

That won't work if the gpio is still configured as input. How about I
add the GPIOD_ASIS change to my patch you remove that and the above from
yours?

best regards
