The question with generic tuner drivers like the tea57XX series is do we always
know this ?
One could argue to proper way to find this out for applications is by looking
at the device topology, either through the media controller framework, or
through sysfs. This is for example what xawtv currently does. We need a better
library to handle this, which also hides from the user whether the media controller
or sysfs is used.

Looks good!
