Subject: [PATCH v2 2/9] drivers: thermal: tsens: Pass around struct tsens_sensor as a constant
Date: Tue, 3 Dec 2019 10:53:23 +0530 [thread overview]
Message-ID: <1d24d634859bebd57e346c3ec4c726a01b7644ba.1575349416.git.amit.kucheria@linaro.org> (raw)
In-Reply-To: <cover.1575349416.git.amit.kucheria@linaro.org>
In-Reply-To: <cover.1575349416.git.amit.kucheria@linaro.org>
All the sensor data is initialised at init time. Lock it down by passing
it to functions as a constant.
Signed-off-by: Amit Kucheria <amit.kucheria@linaro.org>
