usb_hcd_giveback_urb — return URB from HCD to device driver
|struct usb_hcd * hcd,|
|struct urb * urb,|
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.
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.
