#1576283 — [PATCH] thermal: mt8173: minor mtk_thermal.c cleanups

Thermal driver should read TEMP_MSR3 if thermal bank with 4 sensors.
However, Currently thermal driver don't need read TEMP_MSR3 since
thermal controller only use 3 sensors for each thermal bank.

Actually the commit message should state:
Fixes: b7cf0053738c ("thermal: Add Mediatek thermal driver for mt2701.")

...and get backported to v4.9 and v4.10.

Thank you for your review. I would add below commit message on next
version. However, currently 8173 thermal driver would not read TEMP_MSR3
since thermal driver only use 3 sensors on each bank, this patch would
not effect temperature.
Only if 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.")

And don't forget to add stable@vger.kernel.org so that the fix ends up 
in the older kernels as well.
