3.16.84-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Oliver Neukum <[email protected]> commit ab1cbdf159beba7395a13ab70bc71180929ca064 upstream. The driver needs to check the endpoint types, too, as opposed to the number of endpoints. This also requires moving the check earlier.
