Yeah, only the selection API for subdevs is first appearing in kernel 3.5, and it's been already two stable kernel releases since the selection API was introduced: $ git log --oneline v3.0..v3.3 -- Documentation/DocBook/media/v4l/vidioc-g-selection.xml 8af4922 [media] doc: v4l: add documentation for selection API So some backward compatibility code seems to be needed. It's not really a big deal and would saved users headaches. -- Regards, Sylwester -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
