NAME

6       usb_ep_alloc_request - allocate a request object to use with this
7       endpoint
8

SYNOPSIS

10       struct usb_request * usb_ep_alloc_request(struct usb_ep * ep,
11                                                 gfp_t gfp_flags);
12

ARGUMENTS

14       ep
15           the endpoint to be used with with the request
16
17       gfp_flags
18           GFP_* flags to use
19

DESCRIPTION

21       Request objects must be allocated with this call, since they normally
22       need controller-specific setup and may even need endpoint-specific
23       resources such as allocation of DMA descriptors. Requests may be
24       submitted with usb_ep_queue, and receive a single completion callback.
25       Free requests with usb_ep_free_request, when they are no longer needed.
26
27       Returns the request, or null if one could not be allocated.
