Sorry, I likely missed those comments when reviewed the patch series.

As the applied series won't cause regressions, as all init code seem
specific to the new tuner, I won't be reverting the patchsets, but
wait for Antti to be able to do a deeper look on it.

Please submit a patch removing the bogus init code, for Antti's
review.

IMHO, the better here would be to merge both drivers into one, as they
seem to be doing very similar stuff. So, I can't find a good reason
why we should keep both drivers upstream. As dvbsky uses dvb-usb-v2,
the best would be to move the board-specific code from cxusb into
the dvbsky driver, and drop the cxusb driver.

Feel free to submit such patch too.
