Add functions to convert a CString to upper- / lowercase, either in-place or by creating a copy of the original CString. Naming follows the one from the Rust stdlib, where functions starting with 'to' create a copy and functions starting with 'make' perform an in-place conversion. This is required by the Nova project (GSP only Rust successor of Nouveau) to convert stringified enum values (representing different GPU chipsets) to strings in order to generate the corresponding firmware paths.

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.
