[PATCH 2/7] fbdev: atyfb: Use backlight helper

From: Stephen Kitt
Date: Tue Jun 07 2022 - 21:02:59 EST


Instead of retrieving the backlight brightness in struct
backlight_properties manually, and then checking whether the backlight
should be on at all, use backlight_get_brightness() which does all
this and insulates this from future changes.
