[ Upstream commit c408b3d1d9bbc7de5fb0304fea424ef2539da616 ] In cur_state_store(), the new state of the cooling device is received from user-space and is not validated by the thermal core but the same is left for the individual drivers to take care of. Apart from duplicating the code it leaves possibility for introducing bugs where a driver may not do it right. Lets make the thermal core check the new state itself and store the max value in the cooling device structure.

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.
