Rafael J. Wysocki 9a74bfdfd0 cpufreq: Use locking guard and __free() in cpufreq_update_policy()
Instead of using cpufreq_cpu_acquire() and cpufreq_cpu_release() in
cpufreq_update_policy(), which is the last user of these functions,
make it use __free() for policy reference counting cleanup and the
"write" locking guard for policy locking.

No intentional functional impact.

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 reStructuredText 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.
