+Subject: drm/amd/display: Restore backlight brightness after system resume
+
+From: Kai-Heng Feng <kai.heng.feng@canonical.com>
+
+commit bb264220d9316f6bd7c1fd84b8da398c93912931 upstream.
+
+Laptops with AMD APU doesn't restore display backlight brightness after
+system resume.
+
+This issue started when DC was introduced.
+
+Let's use BL_CORE_SUSPENDRESUME so the backlight core calls
+update_status callback after system resume to restore the backlight
+level.
+
+Tested on Dell Inspiron 3180 (Stoney Ridge) and Dell Latitude 5495
+(Raven Ridge).
