v4l2_subdev_alloc_state() and v4l2_subdev_free_state() are not supposed to be used by the drivers. However, we do have a few drivers that use those at the moment, so we need to expose these functions for the time being. Prefix the functions with __ to mark the functions as internal. At the same time, rename them to v4l2_subdev_state_alloc and v4l2_subdev_state_free to match the style used for other functions like video_device_alloc() and media_request_alloc().

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.
