Introduce struct drm_edid and start converting struct edid * to struct drm_edid * in the EDID parsing. The rationale for drm_edid is explained in depth in commit message for patch 3.
Initially, there's little functional benefit in the series, it's mostly just prep work. It's also intended to be relatively straightforward to review.
Later on, we'll add interfaces around drm_edid that let us utilize the actual EDID buffer allocation size as metadata outside of the size contained within the EDID blob. This is a requirement for safely handling HF-EEODB without a huge flag day switch from struct edid usage. See [1] for that work.
BR, Jani.
