3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Felipe Balbi <[email protected]> commit cd423dd3634a5232a3019eb372b144619a61cd16 upstream. due to a HW limitation we have a bounce buffer for ep0 out transfers which are not aligned with MaxPacketSize. On such case we were not increment r->actual as we should. This patch fixes that mistake.
