We only want this control to be available on the qx3 and not on
all cpia1 devices, so you need to add something like the following to
sd_config:

        if (!(id->idVendor == 0x0813 && id->idProduct == 0x0001))
                gspca_dev->ctrl_dis = 1 << LAMPS_IDX;

Where LAMPS_IDX is a define giving the index of V4L2_CID_LAMPS in the
sd_ctrls array, see the ov519 gspca driver for example.

Hans
