I agree, it doesn't look like this needs to be fatal at all.

I'm not sure if it's a good idea to spam the user with borderline nonsensical
warning messages either, in this case (GST_ELEMENT_WARNING is something that
might be shown to the user) - I think it's best to just log a warning in the
debug log and move on.

Also added the EIO error code to the error block above, so please re-test to
make sure things still work with that change, thanks!

    v4l2src: failure to query some optional controls is not a fatal error

    Don't post a (fatal) error message on the bus just because we
    failed to query some control. Fixes issue with built-in
    Suyin Corp webcam for HP notebook (usbid 064e:e28a) on
    OpenSuse 12.1, where querying red/blue balance fails.
