[PATCH] mfd: mc13xxx-core: use complete() instead complete_all()

[Daniel Wagner]

From: Daniel Wagner <daniel.wagner@xxxxxxxxxxxx>

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

mc13xxx_adc_do_conversion()
  struct mc13xxx_adcdone_data adcdone_data

  init_completion(&adcdone_data.done)
  mc13xxx_irq_request()
  wait_for_completeion_interruptible()

                                        mc13xxx_handler_adcdone()
                                          complete()
