`request_internal` must be called with one of the following function pointers: request_firmware(), firmware_request_nowarn(), firmware_request_platform() or request_firmware_direct(). The previous `FwFunc` alias did not guarantee this, which is unsound. In order to fix this up, implement `FwFunc` as new type with a corresponding type invariant.

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.
