Subject: [PATCH] drm/bridge: anx7625: Fix invalid EDID size
DRM checks EDID block count against allocated size in drm_edid_valid function. We have to allocate the right EDID size instead of the max size to prevent the EDID to be reported as invalid.
Fixes 7c585f9a71aa ("drm/bridge: anx7625: use struct drm_edid more")
