Hi all!
I own a USB DVB-T receiver, Terratec Cinergy T XS, (0ccd:0043) which
as far as I can tell from google searches used to work with the old
"em28xx-new" driver.
I've downloaded the old driver from
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/460636/comments/2
and tried to modify the current media_tree drivers accordingly (please
see the attached patch), but I get an error when initializing the frontend:

=====================
As you can see, in my patch I added a couple of printk to
zl10353_init(), but I don't see them in the logs (while I can definitely
see that my em28xx driver is otherwise being used, as with the official
one I don't even see the "zl10353_read_register" line). Can someone
please guide me to debug the issue?
I found an old post to this ML where a user reports a very similar log
file, but without replies:
https://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg13180.html
Any suggestions on what I could try?
Ciao,
Alberto
