Subject: [PATCH 2/4] misc: mic: vop: use complete() instead of complete_all()

From: Daniel Wagner <daniel.wagner@...-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

_vop_remove_device()
  reinit_completion()
  wait_for_completion()
                                        vop_reset()
                                          complete()
