Santosh Mardi bb7dfd9e07 devfreq: check for valid hwmon node during get frequency
Update the condition to check valid hwmon before accessing it because
during parallel usecase of resume call and scaling_max_freq store call
it triggers a call to governor to get frequency and governor tries to
access hwmon node from devfreq pointer and it will be NULL if the
governor has failed to start.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
