[PATCH 4.11 174/197] thermal: mt8173: minor mtk_thermal.c cleanups

From: Greg Kroah-Hartman
Date: Tue May 23 2017 - 18:02:06 EST


4.11-stable review patch. If anyone has any objections, please let me know.

------------------

From: Dawei Chien <dawei.chien@xxxxxxxxxxxx>

commit 05d7839aa290901429d8edcd8f7974c9df2bcaa5 upstream.

If thermal bank with 4 sensors, thermal driver should read TEMP_MSR3.

However, currently thermal driver would not read TEMP_MSR3 since mt8173
thermal driver only use 3 sensors on each thermal bank at the same time,
so this patch would not effect temperature.
Only if mt mt8173 thermal driver use 4 sensors on any thermal bank, would
read third sensor two times, and lose fourth sensor of vale.

Fixes: b7cf0053738c ("thermal: Add Mediatek thermal driver for mt2701.")
