I would prefer to have a proper sysfs for the DVB - I really don't like having 
things randomly scattered about all over sysfs. For example, some of the 
frontends created extra sysfs device files for configuration - these ended up 
attached to some unrelated (to the end-user) i2c device instead of descending 
from the DVB stuff.

At the moment I have temporarily disabled these sysfs files as they weren't 
critical. Perhaps someone on the list might want to look into finishing off 
the sysfs interface so we can resolve this properly once and for all?
