| * | | drm/amd/display: Read AUX channel even if only status byte is returnedLeo (Sunpeng) Li2018-07-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we still go through DC code that does error checking, retries, etc. There's no need for that since DRM already does that for us. This simplifies the code a bit and makes it easier to debug. This also ensures we correctly tell DRM how many bytes have actually been read, as we should.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since there's very few callers of these I've decided to do them all in one patch. With this the unecessarily long drm_mode_connector_ prefix is gone from the codebase! The only exception being struct drm_mode_connector_set_property, which is part of the uapi so can't be renamed. Again done with sed+some manual fixups for indent issues.
