[PATCH 4/4] backlight: tosa: Use backlight helper
From: Stephen Kitt
Date: Tue Jun 07 2022 - 20:38:46 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.
