Subject: [PATCH] telemetry: fix repeat display when callback don't init dict
Date: Thu, 9 Feb 2023 01:25:33 +0000 [thread overview]
Message-ID: <20230209012533.45962-1-fengchengwen@huawei.com> (raw)
When a telemetry callback doesn't initialize the telemetry data
structure and returns a non-negative number, the telemetry will repeat
to display the last result. This patch zero the data structure to avoid
the problem.
Fixes: 6dd571fd07c3 ("telemetry: introduce new functionality")
