We should unlock before returning on this error path.

Dmitry, will you pick this up? It probably should to in for 4.9.
Even though it was prefixed with [media] it wasn't send to linux-media, so it never
ended up in our patchwork.
If you don't want to process this patch, then let me know and I'll take it.
Regards,
Hans

I picked it up. Given it is error handling that should not really fail I
