Hi,
as you proposed that the APIs of host and gadget be made more similar,
I've got questions on the gadget API.
struct usb_request *(*alloc_request) (struct usb_ep *ep,
gfp_t gfp_flags);
void (*free_request) (struct usb_ep *ep, struct usb_request *req);
Why is ep passed to free_request() ? Indeed it is not stored in
struct usb_request. Is there some subtle reason?
alloc_request() is not given the length. Is that because buffers don't
matter for preallocation on the gadget side?
Regards
Oliver
