[PATCH] tuner-core.c improvments and Ymec Tvision TVF8533MF support
tuner-core.c, tuner.h: - tuner-core changed to support multiple I2C devices used on some adapters; - Kconfig now has an option (CONFIG_TUNER_MULTI_I2C) to enable this new behavor; - By default, even enabling CONFIG_TUNER_MULTI_I2C, tuner-core emulates the old behavor, using first I2C device for both FM and TV; - There is a new i2c command (TUNER_SET_ADDR) to allow tuner clients to select I2C address for FM or TV tuner; - Tuner I2C dettach now generates a warning on syslog if failed. tuner-simple.c: - TVision TVF-8531MF and TVF-5533 MF tuner included. It uses, by default, I2C on 0xC2 address for TV and on 0xC0 for Radio. Both TV and FM Radio mode are working.

+ ---help---
+ Some video adapters have more than one tuner inside. This patch
+ enables support for using more than one tuner. This is required
+ for some cards to allow tunning both video and radio.
+ It also improves I2C autodetection for these cards.
+
+ Only few tuners currently is supporting this. More to come.
+
+ It is safe to say 'Y' here even if your card has only one I2C tuner.
