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.
