3.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Felipe Balbi <balbi@xxxxxx>
commit bf17eba7ae1e813b0ad67cb1078dcbd7083b906e upstream.
This reverts commit f2267089ea17fa97b796b1b4247e3f8957655df3.
That commit causes more problem than fixes. Firstly, kfree()
should be called after usb_ep_dequeue() and secondly, the way
things are, we will try to dequeue a request that has already
completed much more frequently than one which is pending.
