[Intel-gfx] [PATCH 00/10] drm/edid: Infoframe cleanups and fixes

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

This series tries to fix some issues with HDMI infoframes. In particular
we can currently send a bogus picture aspect ratio in the infoframe. I
included stuff to to make the infoframe unpakc more robust, evne though
we don't (yet) use it in drm. Additionally I included my earlier "empty"
HDMI infoframe support.

I have further work piled up on top which allows us to precompuet the
infoframes during the atomic check phase. But the series would have
become rather big, so I wanted to post these fixes and cleanups first.

Entire series (with the infoframe precompute) is available here:
