From: Jani Nikula <jani.nikula@intel.com> stable inclusion from stable-v6.6.8 commit a511e851d49e13835f0da022d48e873c8cc15827 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8ST59 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 759f14e20891de72e676d9d738eb2c573aa15f52 upstream. When the separate add modes call was added back in commit c533b5167c7e ("drm/edid: add separate drm_edid_connector_add_modes()"), it failed to address drm_edid_override_connector_update(). Also call add modes there. Reported-by: bbaa <bbaa@bbaa.fun> Closes: https://lore.kernel.org/r/930E9B4C7D91FDFF+29b34d89-8658-4910-966a-c772f320e...
