This cannot work. You refer config struct that is coming outside of
driver. That means, caller must keep stuct, but it does not, and I
really don't even like idea to leave it responsibility of caller. Due to
that you will need copy all config values to driver state before return
from probe().

This patch adds the TS mode as a config option:
- ts_mode added to config struct.
- Possible (interesting) values are
* Parallel mode = 0x06
* Serial mode = 0x03
Currently the modules using this demod only use parallel mode.

Luis
