Subject: [PATCH 0/1] Regression in analogix_anx78xx

commit ff1e8fb68ea0 ("drm/bridge: analogix-anx78xx: Avoid drm_dp_link helpers")
stores the max link rate in a u8, overflowing it.
This will probably prevent the link training from working properly.

I've not tested this patch beyond a simple compile test since I do not own
any devices containing an anx78xx. So please test!

Tobias
