[PATCH 14/15] backlight: tosa: Use backlight helper

From: Sam Ravnborg via B4 Submission Endpoint
Date: Sat Jan 07 2023 - 13:27:54 EST


From: Stephen Kitt <steve@xxxxxxx>

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.
