tda8261: produces unnecessary big debug logs

Hi Folks,
/var/log/warn growed to several mb in two days.
Most of the contents is the output of tda8261.

Aug 21 19:52:10 vdr kernel: [181504.252173] tda8261_get_frequency:
Frequency=2033000
Aug 21 19:51:49 vdr kernel: [181483.256031] tda8261_get_bandwidth:

Bandwidth=40000000
.....
After every channelswitch the module logs something like that.

I tried to add verbose=0 but this didn't help.
What can I do to reduce these messages.
Regards
halim
