thanks for the replys.
so, the new i2c "attach" helper code should
1. be usable for V4L2-DVB multi-functional(hybrid) tuner devices
(or at least co-exist well with them),
2. properly ref-count driver module
to prevent (accidental) 'unload before use' by users.
3. a. block un-binding of the device while in use,
b. support run-time {un-,}binding of the devices
via sysfs by users (to switch drivers?).
Is this right?

I'll look into those drivers' code, to begin with.
(I'm pretty sure those devices are hardly found here in Japan).

All the channels in ISDB-S are scrambled,
unlike ISDB-T(jp) where non-scrambled '1-seg' channels are delivered.
In Japan, it will be considered illegal to desramble them with
a non-authorized software that lacks private copy-guard encryption.
So, unfortunately, there will be no legitimate OSS player for ISDB-S.
