In the Linux kernel, the following vulnerability has been resolved:
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.
