Hi!
[ Upstream commit 0b33a33bd15d5bab73b87152b220a8d0153a4587 ]
The mode_valid field in drm_connector_helper_funcs is expected to be of type: enum drm_mode_status (* mode_valid) (struct drm_connector *connector, struct drm_display_mode *mode);
The mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition.
The return type of mdp4_lvds_connector_mode_valid should be changed from int to enum drm_mode_status.
We don't have kCFI in 5.10, IIRC, so we should not need this.
Best regards, Pavel
