Date: Mon, 10 Oct 2022 16:54:06 +0200	[thread overview]
Message-ID: <20221010145406.118880-5-mattias.ronnblom@ericsson.com> (raw)
In-Reply-To: <20221010145406.118880-1-mattias.ronnblom@ericsson.com>

Update the Event Timer Adapter's service function to report as idle
(i.e., return -EAGAIN) in case no timer events were enqueued to the
event device.
