If the length paramter in len2dlc() exceeds the size of the len2dlc array, we return 0xF. This is equal to the last 16 members of the array. This patch removes these members from the array, uses ARRAY_SIZE() for the length check, and returns CANFD_MAX_DLC (which is 0xf).

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.
