[PATCH] v4l: bug fixes for tuner, cx88 and tea5767
- In CX88 code, some cards needs to have audio reprogramed after changing
video channel;
- Tuner autodetection code seems not to work on some cards. Now,
no_autodetect insmod option allows disabling autodetection code;
- Minor fixes in tea5767 to reduce integer trunc;
- 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.
