struct usb_request * usb_ep_alloc_request (struct usb_ep * ep, int gfp_flags);
Request objects must be allocated with this call, since they normally need controller-specific setup and may even need endpoint-specific resources such as allocation of DMA descriptors. Requests may be submitted with usb_ep_queue, and receive a single completion callback. Free requests with usb_ep_free_request, when they are no longer needed.
Returns the request, or null if one could not be allocated.
