usb_hcd_unlink_urb_from_ep — remove an URB from its endpoint queue
void usb_hcd_unlink_urb_from_ep ( | struct usb_hcd * hcd, |
struct urb * urb); |
Host controller drivers should call this routine before calling
usb_hcd_giveback_urb. The HCD's private spinlock must be held and
interrupts must be disabled. The actions carried out here are required
for URB completion.
