Hi Yaroslav,

the patch below should fix the Oops caused by sd_start() called too early, but
I am not sure about why sd_start() was called from sd_init() for Hercules
webcams in the first place, maybe the snippet marked with:

  /* (from ms-win trace) */

in sd_start() must be moved to sd_init() too.

Let me know if the change below alone is enough and the webcam keeps working,
a test with suspend and resume would good to have too.

Thanks,
   Antonio

I've tested your patch with the latest kernel (3.11.0-rc4) - the webcam 
works OK.  After suspend and resume, the webcam works OK too.
