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:
meson_i2c_xfer_msg()
reinit_completion()
...
/* Start the transfer */
...
wait_for_completion_timeout()
