This comment is mangled, it should look like this:

	/*
	 * Populate...
	 */

And perhaps to clarify that user input takes precedence over CEA you
could list it first in the comment, like so for example:

	/*
	 * Populate picture aspect ratio from either user input (if specified)
	 * or from the CEA mode.
	 */

Also can you please resend patch 3/3 to dri-devel at lists.freedesktop.org
as well so we can see how this is used in a driver?
