[PATCH] v4l: I2C Tuner
- Fixed a trouble on tuner-core that generates erros on computers with more than one TV card. - Rename tuner structures fields. - Tail spaces removed. - I2C cleanups and converged to a basic reference structure. - Removed unused structures. - Fix setting frequency on tda8290. - Added code for TEA5767 autodetection. - Standby mode support implemented. It is used to disable a non used tuner. Currenlty implemented on tea5767. - New macro: set_type disables other tuner when changing mode. - Some cleanups. - Use 50 kHz step when tunning radio for most tuners to improve precision.
