From 2210093478443cd57cff5950379fec31ee8a5f79 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Thu, 30 May 2024 13:01:54 +0300 Subject: [PATCH] drm/exynos/vidi: convert to struct drm_edid Prefer the struct drm_edid based functions for storing the EDID and updating the connector. It would be better if the vidi connection ioctl passed in the EDID size separately instead of relying on the extension count specified in the EDID, but that's what we have to rely on.
