USB_HCD_GIVEBACK_URB(9)	     Host Controller APIs      USB_HCD_GIVEBACK_URB(9)

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.
