Hi Mauro,

We've replaced easycap staging driver with stk1160.
However, stk1160 still misses s-video input support, which I believe
easycap had.

This feature was missing because I couldn't get s-video devices to test with,
but now a couple users have provided the test and the patch is ready.
It's a tiny patch routing saa7115 properly.

I think we should include this feature in v3.7 to complete easycap ->
stk1160 replacement.
Also, it seems to me there's no point in keeping the driver until v3.8,
since there aren't much users out there testing it.

On the other side, I don't want to mess with the flow, so it's
completely up to you.
If you think it's okey, then I can send the patch tonight and
hopefully you can pick
it for your second pull request.

Please let me know.

    Ezequiel
