NAME
       usb_hcd_giveback_urb - return URB from HCD to device driver

SYNOPSIS
       void usb_hcd_giveback_urb(struct usb_hcd * hcd, struct urb * urb, int status);

ARGUMENTS
       hcd
	   host controller returning the URB

       urb
	   urb being returned to the USB device driver.

       status
	   completion status code for the URB.

CONTEXT
       in_interrupt

DESCRIPTION
       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.

       If urb was unlinked, the value of status will be overridden by urb->unlinked. Erroneous short transfers are detected in case the HCD hasn't
       checked for them.
