-Subject: [PATCH] drm/vc4: Notify the firmware when DRM is in charge
-
-Once the call to drm_fb_helper_remove_conflicting_framebuffers() has
-been made, simplefb has been unregistered and the KMS driver is entirely
-in charge of the display.
-
-Thus, we can notify the firmware it can free whatever resource it was
-using to maintain simplefb functional.
