capture_validate_fmt() delegates the media bus format to pixel format conversion to __capture_legacy_try_fmt(). It turns out that this can be simplified quite a lot: - The format lookup from media bus code can be performed by the recently added capture_find_format() function instead of receiving the information from a side effect of __capture_legacy_try_fmt(). - The validation of the pixel format size isn't needed, as they duplicate the validation of the compose rectangle. The pixel format size is directly derived from the size of the incoming stream, which is stored in the compose rectangle. If the compose rectangle is valid, the pixel format size will be valid too. By removing the validation of the pixel format size and using capture_find_format() to lookup the format, we can stop using __capture_legacy_try_fmt() and simplify capture_validate_fmt().

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.
