Rafael J. Wysocki a44d0904d6 cpufreq: intel_pstate: Rearrange show_no_turbo() and store_no_turbo() 
[ Upstream commit c626a43845 ]

Now that global.turbo_disabled can only change at the cpufreq driver
registration time, initialize global.no_turbo at that time too so they
are in sync to start with (if the former is set, the latter cannot be
updated later anyway).

That allows show_no_turbo() to be simlified because it does not need
to check global.turbo_disabled and store_no_turbo() can be rearranged
to avoid doing anything if the new value of global.no_turbo is equal
to the current one and only return an error on attempts to clear
global.no_turbo when global.turbo_disabled.

While at it, eliminate the redundant ret variable from store_no_turbo().

No intentional functional impact.

README 

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.
