Subject: [PATCH 1/4] platform/x86: acer-wmi: Use backlight helper
Date:   Tue,  7 Jun 2022 20:46:32 +0200

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.
