static_call_update() had stronger type requirements than regular C, relax them to match. Instead of requiring the @func argument has the exact matching type, allow any type which C is willing to promote to the right (function) pointer type. Specifically this allows (void *) arguments. This cleans up a bunch of static_call_update() callers for PREEMPT_DYNAMIC and should get around silly GCC11 warnings for free.

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.
