skrll 197d83126f Protect access of urb->hcpriv by adapting the following change from the ... Raspberry PI dwc_otg driver. 38753ce72d dwc_otg: prevent OOPSes during device disconnects The dwc_otg_urb_enqueue function is thread-unsafe. In particular the access of urb->hcpriv, usb_hcd_link_urb_to_ep, dwc_otg_urb->qtd and friends does not occur within a critical section and so if a device was unplugged during activity there was a high chance that the usbcore hub_thread would try to disable the endpoint with partially- formed entries in the URB queue. This would result in BUG() or null pointer dereferences. Fix so that access of urb->hcpriv, enqueuing to the hardware and adding to usbcore endpoint URB lists is contained within a single critical section.		2014-01-02 15:54:10 +00:00
