Right, thanks for pointing this out!

Attached is the updated patch, please use this one instead.

Thanks!

Duplicate functionality with the gspca_zc3xx driver, zc0301 only
supports 2 USB-ID's (because it only supports a limited set of
sensors) wich are also supported by the gspca_zc3xx driver
(which supports 53 USB-ID's in total).
