12   This function implements a callback useable as the -&gt;mode_set_base used
13   required by the crtc helpers. The driver must provide the atomic plane helper
14   functions for the primary plane.
15   </p><p>
16
17   This is a transitional helper useful for converting drivers to the atomic
18   interfaces.
