It's inevitable to switch over to kernel-i2c for the saa7146 based cards 
and let dvb-i2c vanish.

For the stv0299 and the tda1004x drivers, I already did these changes, 
ie. they use the kernel-i2c interface and the kernel-i2c adapters 
registered by av7110 and budget.

The big plus is, that kernel-i2c automatically does all the sysfs and 
kobject foo. In addition, it's very easy to use the firmware-loading 
facilities in conjunction with kernel-i2c.

Please have a look at the tda1004x driver, where firmware loading is 
implemented through the device member of the i2c client object.

In the short term, we should at least convert all drivers that need 
firmware to kernel-i2c.
