When CONFIG_V4L2 is built as a loadable module, the new video mux driver
fails to link as built-in code:
drivers/media/platform/video-mux.o: In function `video_mux_remove':
video-mux.c:(.text+0x24): undefined reference to `v4l2_async_unregister_subdev'
drivers/media/platform/video-mux.o: In function `video_mux_probe':
video-mux.c:(.text+0x800): undefined reference to `v4l2_subdev_init'
video-mux.c:(.text+0xa10): undefined reference to `v4l2_async_register_subdev'
This makes it use the same Kconfig dependency as all the other users of
the VIDEO_V4L2_SUBDEV_API symbol.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
