I looked for a race here, but I do not find a race between open and release, since a refcount of "
file_data->data->kref" is always hold by usbtmc_probe/disconnect.However I see a race between
usbtmc_openandusbtmc_disconnect. Are these callback functions called mutual exclusive?
No, they are not.

I'm not sure, but if not, then I think we have the same problem in
usb-skeleton.c
In usb-skeleton.c a race exists. You are right.
