Now that all drivers use v4l2_fh, we can drop the V4L2_FL_USES_V4L2_FH checks through the V4L2 core. To ensure that all new drivers use v4l2_fh, keep setting the V4L2_FL_USES_V4L2_FH flag in v4l2_fh_init(), and verify it is set after the .open() file operation returns.

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.
