Ray Wu 2686a0c0aa drm/amd/display: Check for tg ops in dce110_set_avmute ... Some older DCE timing generators do not implement is_tg_enabled in their ops table. Calling it unconditionally when waiting for AV mute frames causes a NULL pointer dereference on Southern Islands dGPUs when turning the display off over HDMI. Check that tg and the required ops exist before waiting for frames.
