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
