For an example, if +KVM mouse events are sent when the host is in text mode, queueing +of end point messages will be dropped with this message: + +configfs-gadget gadget: usb_ep_queue error on int endpoint -108 + +This case is very usual case in BMC since BMC can control power +status of the host, so this commit suppress the error printing outs +with making HID gadget driver drop events quietly in the case. + +This should be a downstream only customization.
