Hi Shuah,
I find this by code review. Do i really need to add this to commit log? This look like a little weird.
Great. Good find.
It is important to understand how the problem is found. Please add it
the change log. We usually expect dmesg or such info. that revealed
refcount leak, since this one is found during code review, we would
like to see that information the commit log.
Also please remember to avoid top posting.

usb_get_dev() is called in stub_device_alloc(). When stub_probe() fails
after that, usb_put_dev() needs to be called to release the reference.
Fix this by moving usb_put_dev() to sdev_free error path handling.
