| Subject: media: hdpvr: register the video node at the end of probe |
| |
| From: Hans Verkuil <hans.verkuil@cisco.com> |
| |
| commit 280847b532433ffe7a22795f926327805a127162 upstream. |
| |
| Video nodes can be used at once after registration, so make sure the full |
| initialization is done before registering them. |
