commit 48c3375c5f upstream.
This patch (as1640) fixes a memory leak in xhci-hcd. The urb_priv
data structure isn't always deallocated in the handle_tx_event()
routine for non-control transfers. The patch adds a kfree() call so
that all paths end up freeing the memory properly.
This patch should be backported to kernels as old as 2.6.36, that
contain the commit 8e51adccd4 "USB: xHCI:
Introduce urb_priv structure"
