This adds a new quirk NVME_QUIRK_NO_TEMP_THRESH_CHANGE to avoid changing the value of the temperature threshold feature for specific devices that show undesirable behavior. Guenter reported: "On my Intel NVME drive (SSDPEKKW512G7), writing any minimum limit on the Composite temperature sensor results in a temperature warning, and that warning is sticky until I reset the controller. It doesn't seem to matter which temperature I write; writing -273000 has the same result." The Intel NVMe has the latest firmware version installed, so this isn't a problem that was ever fixed.

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.
