Series drm/connector: make mode_valid() callback accept const mode pointer | expand

Commit Message

Make hda_get_mode_idx() take a const struct drm_display_mode pointer
instead of just raw struct drm_display_mode. This is a preparation to
converting the mode_valid() callback of drm_connector to take a const
struct drm_display_mode argument.
