[linux-dvb] Twinhan 1027 (once again)

[Sergey Ivanov]

When v4l-dvb starts to support this card? You already have well tested patch
for this purpose. But it still "experimental". I had one doubt, i'm not sure
if we need all of those chips, that patch contain, cos this card has only
cx88x & mb86a16, so i exclude em, and it looks work.
