From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Put the vblank timestamping constants update loop into its own function. It has no business living inside drm_atomic_helper_update_legacy_modeset_state() so we'll be wanting to move it out entirely. As a first step we'll still call it from drm_atomic_helper_update_legacy_modeset_state().
