From 25ba9429e0f40d3b725781e70d2d6b9ce47a0df4 Mon Sep 17 00:00:00 2001 From: Stephen Kitt Date: Tue, 7 Jun 2022 20:10:22 +0200 Subject: drm/bridge: parade-ps8622: Use backlight helper backlight_properties.fb_blank is deprecated. The states it represents are handled by other properties; but instead of accessing those properties directly, drivers should use the helpers provided by backlight.h. 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.
