commit552abb884eupstream. After commit18c49926c4("cpufreq: Add QoS requests for userspace constraints") the return value of freq_qos_update_request(), that can be 1, passed by cpufreq_boost_set_sw() to its caller sometimes confuses the latter, which only expects to see 0 or negative error codes, so notice that cpufreq_boost_set_sw() can return an error code (which should not be -EINVAL for that matter) as soon as the first policy without a frequency table is found (because either all policies have a frequency table or none of them have it) and rework it to meet its caller's expectations.

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.
