The call to mlxsw_thermal_module_temp_and_thresholds_get passes a NULL
pointer for the temperature and this can be dereferenced in this function
if the mlxsw_reg_query call fails. The simplist fix is to pass the
address of dummy temperature variable instead of a NULL pointer.
Addresses-Coverity: ("Explicit null dereferenced")

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.
