According to v4l2 request api specifications, it's allowed to skip
control if its content isn't changed for performance reasons. Cedrus
driver predates that, so it has implemented mechanism to check if all
required controls are included in one request.
Conform to specifications with removing that mechanism.
Note that this mechanism with static required flag isn't very good
anyway because need for control is usually signaled in other 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.
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.
