[PATCH 0/5] treewide: add missing MODULE_DESCRIPTION() macros

Since commit 1fffe7a34c89 ("script: modpost: emit a warning when the
description is missing"), a module without a MODULE_DESCRIPTION() will
result in a warning when built with make W=1.

Recently, multiple developers have been eradicating these warnings
treewide, and I personally submitted almost 300 patches over the past
few months. Almost all of my patches landed by 6.11-rc1, either by
being merged in a 6.10-rc or by being merged in the 6.11 merge
window. However, a few of my patches did not land.

In some cases I see them in linux-next, but they did not land during
the merge window. I'm still monitoring those.

In a few cases I have not had any feedback that the patches have been
accepted into a maintainer's tree. At the advice of Greg KH I've
consolidated those patches into this single series with the hope these
can still land before 6.11-final.

[PATCH 3/5] cpufreq: powerpc: add missing MODULE_DESCRIPTION() macros

With ARCH=powerpc, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in
drivers/cpufreq/ppc-cbe-cpufreq.o
WARNING: modpost: missing MODULE_DESCRIPTION() in
drivers/cpufreq/powernv-cpufreq.o

Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().

This includes three additional files which, although they did not
produce a warning with the powerpc allmodconfig configuration, may
cause this warning with specific options enabled in the kernel
configuration.
