The driver failed to stop its read URB on disconnect, something which could lead to a use-after-free in the completion handler after driver unbind in case the character device has been closed.

This one isn't needed in any stable tree. As we discussed before, the skeleton driver is only there for documentation purposes.
I'll drop this, but I'm curious: doesn't this mean that users will build on buggy example code?
