Boot Error: intel_panel_get_max_backlight [OK]

[Andyun]

It is normal?
When the system is booting:
[ 9.091415] [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero.
[ 9.453304] [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero.

I have the same on my girlfriend's laptop. Does seems to pose any problem further.

I think JRD meant to write "does not seem to pose any problem".

And it doesn't. This message is targeted at intel drm kernel developers so that they should update their code to keep up with changes in the linux kernel. It might look scary but it doesn't mean that something is not working right.

Yes gapan, I forgot the "not".

Well that means the message will probably disappear on the next kernel upgrade.
