[PATCH 3.4 129/134] media: hdpvr: register the video node at the end of probe

[Greg Kroah-Hartman]

3.4-stable 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.
