[ Upstream commit364ffd2537] There are fields 'last_hwmon_state' and 'last_thermal_state' in the structure 'emc2305_cdev_data', which respectively store the cooling state set by the 'hwmon' and 'thermal' subsystem, and the driver author hopes that if the state set by 'hwmon' is lower than the value set by 'thermal', the driver will just save it without actually setting the pwm. Currently, the 'last_thermal_state' also be updated by 'hwmon', which will cause the cooling state to never be set to a lower value. This patch fixes that.

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.
