Switching back to Linux 4.8.13 results in a working USB-DVB, and the error/warning message don't show up.
The configs are the same, so it seems a issue with the module(s) (si2168?).

All USB bugs should be sent to the firstname.lastname@example.org mailing
list, and not entered into bugzilla. Please bring this issue up there,
if it is still a problem in the latest kernel release.
Fixed on 4.11.
