- Bug fixes:
1) On CX88 code, some cards needs to have audio reprogramed after
changing video channel;
2) Tuner autodetection code seems not to work on some cards. Now,
no_autodetect insmod option allows disabling autodetection code;
3) Minor fixes at tea5767 to reduce integer trunc;
4) There are some new Pixelview Ultra Pro cards that doesn't use TEA5767
for radio. As autodetection is capable of checking for tea, radio tuners
and addresses removed.
- CX88 version number incremented.
