Enric Balletbo i Serra a75a8aabb2 Revert "thermal: mediatek: fix register index error" [ Upstream commit a8f62f183021be389561570ab5f8c701a5e70298 ] This reverts commit `eb9aecd90d` The above patch is supposed to fix a register index error on mt2701. It is not clear if the problem solved is a hang or just an invalid value returned, my guess is the second. The patch introduces, though, a new hang on MT8173 device making them unusable. So, seems reasonable, revert the patch because introduces a worst issue. The reason I send a revert instead of trying to fix the issue for MT8173 is because the information needed to fix the issue is in the datasheet and is not public. So I am not really able to fix it. Fixes the following bug when CONFIG_MTK_THERMAL is set on MT8173 devices.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
