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
nau7802_read_irq()
reinit_completion()
nau7802_read_conversion()
wait_for_completion_interruptible_timeout()
nau7802_eoc_trigger()
complete()
