Geert Uytterhoeven e17a5b8192 drm/radeon/r100: Handle unknown family in r100_cp_init_microcode()
[ Upstream commit c6dbab46324b1742b50dc2fb5c1fee2c28129439 ]

With -Werror:

    In function ‘r100_cp_init_microcode’,
	inlined from ‘r100_cp_init’ at drivers/gpu/drm/radeon/r100.c:1136:7:
    include/linux/printk.h:465:44: error: ‘%s’ directive argument is null [-Werror=format-overflow=]

	  |                 ^~~~~~

Fix this by converting the if/else if/... construct into a proper
switch() statement with a default to handle the error case.

As a bonus, the generated code is ca. 100 bytes smaller (with gcc 11.4.0
targeting arm32).

README

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.
