Except the dvb-pll code will check for tuner presence when attaching, while the old code didn't. This tuner appears to not be behind the stv0297's I2C gate but is instead on a different I2C adapter provided by the flexcop chip. The old code would turn the I2C gate off each time the tuner was used. I've changed it to turn the gate off when the tuner is attached and then disable the gate control function. This should result in the gate staying off, which should be even better.
