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()
