NAME
       usb_ep_alloc_request - allocate a request object to use with this
       endpoint

SYNOPSIS
       struct usb_request * usb_ep_alloc_request(struct usb_ep * ep,
						 gfp_t gfp_flags);

ARGUMENTS
       ep
	   the endpoint to be used with with the request

       gfp_flags
	   GFP_* flags to use

DESCRIPTION
       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.
