This wouldn't be the first time that a vendor released a device without changing the product id, whose earlier revisions used an mt352, and later revisions used a zl10353.
I recommend that you handle it in the following way:
static int anysee_zl35x_frontend_attach(struct dvb_usb_adapter *adap)
/* any device-specific stuff may go here */
if (((adap->fe = dvb_attach(mt352_attach, &anysee_mt352_config,
&adap->dev->i2c_adap)) != NULL) ||
((adap->fe = dvb_attach(zl10353_attach,
&adap->dev->i2c_adap)) != NULL))
The _attach functions of each module tests the id register to ensure that the proper demod is actually present -- a few drivers are already doing this, such as dvb-usb-cxusb and dvb-bt8xx. I think there are others as well...
