[PATCH v2 16/16] backlight: use backlight_is_blank() in all backlight drivers
Sam Ravnborg
sam at ravnborg.org
Sun May 17 19:01:39 UTC 2020
Replaces the open-coded checks of the state etc.,
with the backlight_is_blank() helper.
This increases readability of the code and align
the functionality across the drivers.
v2:
- Fixed so changelog is readable
