Subject: [PATCH v2 0/1] Regression in analogix_anx78xx
Date: Sun, 8 Mar 2020 16:22:37 +0100 [thread overview]
Message-ID: <20200308152238.1294229-1-t.schramm@manjaro.org> (raw)
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.
I've not tested this patch beyond a simple compile test since I do not own
any devices containing an anx78xx. So please test!
Best regards,
Tobias
Changelog:
v2: Skip forward and back conversion to/from link rate
