Did you see what is magic used those devices?
None. They have the same problem, creating hard module dependencies
even if they use dvb_attach() and CONFIG_MEDIA_ATTACH is set:
bjorn@canardo:~$ modinfo b2c2-flexcop
filename: /lib/modules/2.6.32-5-amd64/kernel/drivers/media/dvb/b2c2/b2c2-flexcop.ko

vermagic: 2.6.32-5-amd64 SMP mod_unload modversions
parm: debug:set debug level (1=info,2=tuner,4=i2c,8=ts,16=sram,32=reg (|-able)). (debugging is not enabled) (int)
parm: adapter_nr:DVB adapter numbers (array of short)
This probably means that a generic i2c_tuner wrapper, similar to
dvb_attach, would be useful.
For the cxd2820r it is also possible to return I2C adapter as pointer
from dvb_attach like pointer to FE0 is carried for FE1 dvb_attach. What
you think about that?

Antti
