[PATCH 4/4] misc: tifm: 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

tifm_7xx1_resume()
  DECLARE_COMPLETION_ONSTACK(finish_resume)
  fm->finish_me = finish_resume
  /* enable irq */
  wait_for_completion_timeout(finish_resume)

                                        tifm_7xx1_isr()
                                          complete(fm->finish_me)
