[PATCH] v4l: tuner improvements
*tuner-core.c: - some tuner_info msgs will be generated only if insmod opt tuner_debug enabled. - Implemented tuner-core support for VIDIO_S_TUNER to allow changing mono/stereo mode - Remove unneeded config options. - I2C_CLIENT_MULTI option removed. - support for Philips FMD12ME hybrid tuner - allow to initialize with another tuner - Move PHILIPS_FMD initialization code to set_type function, * tda8290: - Fix dumb error in tda8290 tunning. - Radio tuner uses high-precision step instead of 62.5 KHz. *tea5767.c: - tuner_info msgs will be generated only if insmod tuner option tuner_debug enabled. - some cleanups for better reading. - Radio tuner uses high-precision step instead of 62.5 KHz. - Changing radio mode stereo/mono for tea5767 working. *tuner-simple.c: - TNF9533-D/IF UHF fixup. - Radio tuners now uses high-precision step instead of 62.5 KHz. *mt20xx.c: - Radio tuner uses high-precision step instead of 62.5 KHz. *tda9887.c: - tab and blank spaces corrections.
