[ Upstream commitd2294461b9] sparse reports sound/soc/samsung/rx1950_uda1380.c:131:18: warning: symbol 'gpiod_speaker_power' was not declared. Should it be static? sound/soc/samsung/rx1950_uda1380.c:231:24: warning: symbol 'rx1950_audio' was not declared. Should it be static? Both gpiod_speaker_power and rx1950_audio are only used in rx1950_uda1380.c, so their storage class specifiers should be static.

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.
