Re: [PATCH 3/8] drm/ingenic: Use standard drm_atomic_helper_commit_tail

By making the CRTC's .vblank_enable() function return an error when it
is known that the hardware won't deliver a VBLANK, we can drop the
ingenic_drm_atomic_helper_commit_tail() function and use the standard
drm_atomic_helper_commit_tail() function instead.

Hi,
if this function is removed, shouldn't:
static struct drm_mode_config_helper_funcs ingenic_drm_mode_config_helpers = {
.atomic_commit_tail = ingenic_drm_atomic_helper_commit_tail,
};
be updated as well?

I've not seen it in the serie.

Just my 2v.
