USB_HCD_GIVEBACK_URB(9) Host Controller APIs USB_HCD_GIVEBACK_URB(9)NAMEusb_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.
