Manaf Meethalavalappu Pallikunhi dbbc8aeaf7 thermal: core: Reset previous low and high trip during thermal zone init
[ Upstream commit 99b63316c39988039965693f5f43d8b4ccb1c86c ]

During the suspend is in process, thermal_zone_device_update bails out
thermal zone re-evaluation for any sensor trip violation without
setting next valid trip to that sensor. It assumes during resume
it will re-evaluate same thermal zone and update trip. But when it is
in suspend temperature goes down and on resume path while updating
thermal zone if temperature is less than previously violated trip,
thermal zone set trip function evaluates the same previous high and
previous low trip as new high and low trip. Since there is no change
in high/low trip, it bails out from thermal zone set trip API without
setting any trip. It leads to a case where sensor high trip or low
trip is disabled forever even though thermal zone has a valid high
or low trip.

During thermal zone device init, reset thermal zone previous high
and low trip. It resolves above mentioned scenario.

README

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.
