3.10-stable review patch. If anyone has any objections, please let me know.
------------------ From: Roger Quadros <[email protected]> commit 47a64a13d54f6c669b00542848d5550be3d3310e upstream. Set the ehci->resuming flag for the port we receive a remote wakeup on so that resume signalling can be completed. Without this, the root hub timer will not fire again to check if the resume was completed and there will be a never-ending wait on on the port. This effect is only observed if the HUB IRQ IN does not come after we have initiated the port resume.
