-/* Okay, this is some magic that I worked out and the reasoning behind it...
-
-   The biggest problem with any USB device is of course: "what to do
-   when the user unplugs the device while it is in use by an application?"
-   We have several options:
-   1) Curse them with the 7 plagues when they do (requires divine intervention)
-   2) Tell them not to (won't work: they'll do it anyway)
-   3) Oops the kernel (this will have a negative effect on a user's uptime)
-   4) Do something sensible.
-
-   Of course, we go for option 4.
-
-   It happens that this device will be linked to two times, once from
-   usb_device and once from the video_device in their respective 'private'
-   pointers. This is done when the device is probed() and all initialization
-   succeeded. The pwc_device struct links back to both structures.
-
-   When a device is unplugged while in use it will be removed from the
-   list of known USB devices; I also de-register it as a V4L device, but
-   unfortunately I can't free the memory since the struct is still in use
-   by the file descriptor. This free-ing is then deferend until the first
-   opportunity. Crude, but it works.
-
-   A small 'advantage' is that if a user unplugs the cam and plugs it back
-   in, it should get assigned the same video device minor, but unfortunately
-   it's non-trivial to re-link the cam back to the video device... (that
-   would surely be magic! :))
