Subject: [PATCH 1/3] thermal/drivers/qcom: Remove get_trend function
Date:   Thu, 16 Jun 2022 22:25:35 +0200
Message-Id: <20220616202537.303655-1-daniel.lezcano@linaro.org>

There is a get_trend function which is a wrapper to call a private
get_trend function. However, this private get_trend function is not
assigned anywhere.

Remove this dead code.
