10   This aligns the pitch and size arguments to the minimum required. This is
11   an internal helper that can be wrapped by a driver to account for hardware
12   with more specific alignment requirements. It should not be used directly
13   as the -&gt;<code class="function">dumb_create</code> callback in a DRM driver.
