The new interface also needs to be documented in the media DocBook: section 4
describes all the interfaces, so a new one should be added here.
Sorry, just realized this.
I recommend that you grep for swradio:
git grep swradio Documentation/DocBook/media
and add a line there for v4l-touch as well. It also looks like a new interface
define is needed as a media type.
