Now that all drivers access the v4l2_fh from the file structure, there is no need to pass it as an explicit argument to ioctl handlers. Set the argument to NULL in the __video_do_ioctl() function, and rename the 'fh' argument in the ioctl handler declarations to 'priv' indicate it does not contain a file handle. The argument could be removed altogether with a mechanical change (probably using coccinelle), but there are plans to pass a new argument to the ioctl handlers in the near future. The tree-wide change to remove the argument, only to add another one soon after, would be too much churn. While at it, fix argument alignment in vidioc_try_fmt_vid_out_overlay().

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 reStructuredText 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.
