sugov_cpu_is_busy() is used to avoid decreasing performance level while the CPU is busy and called by sugov_update_single_freq() and sugov_update_single_perf(). Both callers repeat the same pattern to first test for uclamp and then the business. Let's refactor so that the tests aren't repeated. The new helper is named sugov_hold_freq() and tests both the uclamp exception and CPU business. No functional changes. This will make adding more exception conditions easier.

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.
