Something weird is wrong with this series. I have a DC30, but loading this with:

modprobe zr36067 card=3

results in this error message in the kernel log:

[   58.645557] zr36067: module is from the staging directory, the quality is unknown, you have been warned.
[   58.646658] zr36067 0000:03:00.0: Zoran MJPEG board driver version 0.10.1
[   58.646793] zr36067 0000:03:00.0: Zoran ZR36057 (rev 1), irq: 18, memory: 0xf4000000
[   58.648821] zr36067 0000:03:00.0: Initializing i2c bus...

[   58.737445] zr36067 0000:03:00.0: Fail to get encoder

This works before, so why this is now failing is not clear to me.

It does work with 'card=0', but I really have a DC30.

If I test with 'card=0' then the rmmod issue is now solved.

Regards,

	Hans
