Clang warns:
drivers/staging/vc04_services/bcm2835-camera/controls.c:59:18: warning:
variable 'mains_freq_qmenu' is not needed and will not be emitted
[-Wunneeded-internal-declaration]
static const s64 mains_freq_qmenu[] = {
^
1 warning generated.
This is because mains_freq_qmenu is currently only used in an ARRAY_SIZE
macro, which is a compile time evaluation in this case. Avoid this by
adding mains_freq_qmenu as the imenu member of this structure, which
matches all other controls that uses the ARRAY_SIZE macro in v4l2_ctrls.
This turns out to be a no-op because V4L2_CID_MPEG_VIDEO_BITRATE_MODE is
defined as a MMAL_CONTROL_TYPE_STD_MENU, which does not pass the imenu
definition along to v4l2_ctrl_new in bm2835_mmal_init_controls.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
