usb_hcd_giveback_urb: return URB from HCD to device driver
usb_hcd_giveback_urb - return URB from HCD to device driver
void usb_hcd_giveback_urb(struct usb_hcd
*hcd, struct urb *urb, int status);
- host controller returning the URB
- urb being returned to the USB device driver.
- completion status code for the URB.
This hands the URB from HCD to its USB device driver, using its completion function. The HCD has freed all per-urb resources (and is done using urb->hcpriv). It also released all HCD locks; the device driver won't cause problems if it frees, modifies, or resubmits this URB.
