This is a bit confusing since until this patch the .off() code is
actually called from intel_crtc_disable, which calls
intel_put_shared_dpll(). I think what you intended to say here is that
intel_shared_dpll_commit() has the same effect as put_shared_dpll(), so
it is safe to remove that call, at which point the .off() hook is not
necessary anymore.

Maybe split this to a separate patch?
