    V4L/DVB (3693): Fix msp3400c and bttv stereo/mono/bilingual detection/handling · 0020d3ef
    Hans Verkuil authored
    - msp3400c did not detect the second carrier, thus being always mono.
    - properly mute the msp3400c while detecting the carrier.
    - fix checks on the presence of scart2/3 inputs and scart 2 output.
    - implement proper audio mode fallbacks for msp3400c/d, identical to the
      way msp3400g works.
    - MODE_STEREO no longer produces dual languages when set for a bilingual
      transmission, instead it falls back to LANG1. Use LANG1_LANG2 to hear
      both languages of a bilingual transmission. This is much more intuitive
      for the user and is in accordance with the preferred usage in the v4l2
      specification.
    - bttv tried to implement v4l2 calls with v4l1 calls to the i2c devices,
      completely mangling the audmode/rxsubchans handling. v4l2 calls now do
      v4l2 calls to the i2c devices.
    - fixed broken i2c_vidiocschan in bttv.
    - add start/end lines to LOG_STATUS.
