Subject: [PATCH 6/7] platform/chrome: cros_ec_proto: add Kunit tests for get_sensor_count
Date: Wed, 22 Jun 2022 04:10:39 +0000 [thread overview]
Message-ID: <20220622041040.202737-7-tzungbi@kernel.org> (raw)
In-Reply-To: <20220622041040.202737-1-tzungbi@kernel.org>
cros_ec_get_sensor_count() gets number of MEMS sensors.
Add Kunit tests for cros_ec_get_sensor_count().
