Please, please, please, can we concentrate on the subject?
What I did with the other out-of-tree em28xx-new driver was that
I printed out the urb->kref.refcount before and after each urb operation.
The result was that when the urb->complete function is called, the reference
count was still 2, instead of 1.
I could imagine three possible errors:
1. there is a bug in uvcvideo driver
2. there is a bug in v4l framework
3. there is a bug in usb subsystem
It would be good if someone who have a deeper knowledge than me on these fields
could
give some hints or debug patches which would lead us closer to the solution.
