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:

bcm_iproc_i2c_xfer_single_msg()
  reinit_completion()
  ...
  (activate the transfer)
  ...
  wait_for_completion_timeout()
