V4L/DVB (7227): saa7134: fixed DVB-S support for Medion/Creatix CTX948
The I2C bus interface of the LNB supply sits behind the i2c gate of the
tda10086, so wrappers were necessary for the set_voltage functions.
For the time being, the board will show up as MD8800
Many thanks to Hermann Pitton for his help
