Hello,
This small patch series attemps at decoupling EDID retrieval from drm_connector, following a discussion with Daniel Vetter [1]. While working on this I noticed a few issues with EDID retrieval, which I have attempted to fix in patches 1/5 to 4/5. Patch 5/5 then tries to decouple the EDID retrieval from drm_connector, in what I think is a pretty bad way. I would like to discuss this further to see if a) there's an interest, and b) someone has a better idea :-)
Regardless of the outcome of the discussion on patch 5/5, the first four patches are candidates for upstreaming as they try to address existing issues (they may also introduce new bugs, but hopefully they will be pointed out during review).
The patches are available at
