[PATCH 1/4] misc: mic: scif: use complete() instead of complete_all()

[Daniel Wagner <wagi@monom.org>]

From: Daniel Wagner <daniel.wagner@bmw-carit.de>

There is only one waiter for the completion, therefore there
is no need to use complete_all(). Let's make that clear by
using complete() instead of complete_all().

The usage pattern of the completion is:

waiter context                          waker context

scif_get_node_info()
  DECLARE_COMPLETION_ONSTACK(node_info);
  msg->payload[3] = node_info
  scif_nodeqp_send()
  wait_for_completion(node_info)

                                        scif_get_node_info_resp()
                                          node_info = msg->payload[3]
                                          complete(node_info)
