Rafael J. Wysocki a8a2617744 thermal: core: Call monitor_thermal_zone() if zone temperature is invalid 
Commit 202aa0d4bb ("thermal: core: Do not call handle_thermal_trip()
if zone temperature is invalid") caused __thermal_zone_device_update()
to return early if the current thermal zone temperature was invalid.

This was done to avoid running handle_thermal_trip() and governor
callbacks in that case which led to confusion.  However, it went too
far because monitor_thermal_zone() still needs to be called even when
the zone temperature is invalid to ensure that it will be updated
eventually in case thermal polling is enabled and the driver has no
other means to notify the core of zone temperature changes (for example,
it does not register an interrupt handler or ACPI notifier).

Also if the .set_trips() zone callback is expected to set up monitoring
interrupts for a thermal zone, it has to be provided with valid
boundaries and that can only happen if the zone temperature is known.

Accordingly, to ensure that __thermal_zone_device_update() will
run again after a failing zone temperature check, make it call
monitor_thermal_zone() regardless of whether or not the zone
temperature is valid and make the latter schedule a thermal zone
temperature update if the zone temperature is invalid even if
polling is not enabled for the thermal zone.

Fixes: 202aa0d4bb ("thermal: core: Do not call handle_thermal_trip() if zone temperature is invalid")

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 reStructuredText 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.
