Leo (Sunpeng) Li edf6ffe4f4 drm/amd/display: Read AUX channel even if only status byte is returned ... [Why] get_channel_status() can return 0 in returned_bytes, and report a successful operation result. This is because it prunes the first status byte out. This was preventing read_channel_reply() from being called (due to the faulty condition), and consequently preventing the AUX reply status from being set. [How] Fix the conditional so that it accounts for when get_channel_status() returns 0 bytes read. [Fixes] Fixes possible edid read failures during S3 resume, where we are now relying on DRM's DP AUX handling.
