Hi guys,

I have written a driver for Laika (winux-it.com) based on Patrick's
dvb-usb framework. I am using the tda1004x frontend module to control
the tda10046 demodulator.

When checking my logs, it seems that my device is being unregistered
during initialization? It happens after tda10046h_set_bandwidth() the
the tda1004x code. Should this be happening? For the record, tuning
fails.

The log format is (address, index): data. Below is a portion of the
log, I have attached the full log for those interested.
