3.2.52-rc1 review patch. If anyone has any objections, please let me know.

------------------

From: Hans Verkuil <hans.verkuil@xxxxxxxxx>

commit 280847b532433ffe7a22795f926327805a127162 upstream.

Video nodes can be used at once after registration, so make sure the full
initialization is done before registering them.
