[Intel-gfx] [PATCH] drm/i915/edid: convert DP, HDMI and LVDS to drm_edid
Jani Nikula
jani.nikula at intel.com
Thu Jun 23 07:27:56 UTC 2022
Convert all the connectors that use cached connector edid and
detect_edid to drm_edid.
v3: Don't leak vga switcheroo EDID in LVDS init (Ville)
v2: Don't leak opregion fallback EDID (Ville)
