Dont we need to make sure initial_watermarks is present or !NULL before calling it
like we do in all other hooks?

Also some places we use intel_crtc vs crtc even though both are of type struct intel_crtc*,
either in this patch or another cleanup patch we should change it all to keep either crtc or
intel_crtc else there is a confusion between crtc being of type intel_crtc or drm_crtc

What do you think?
But that could be a separate change so after adding a check for if (dev_priv->display.initial_watermarks)
in valleyview_crtc_enable(),
