Subject: linux-next: build failure after merge of the kbuild tree

Hi all,

After merging the kbuild tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

ERROR: modpost: missing MODULE_DESCRIPTION() in lib/kunit/backtrace-suppression-test.o
ERROR: modpost: missing MODULE_DESCRIPTION() in lib/slub_kunit.o

Caused by commits

  19f3496e6241 ("kunit: add test cases for backtrace warning suppression")

from the mm-nonmm-unstable branch of the mm tree and

  1f9f78b1b376 ("mm/slub, kunit: add a KUnit test for SLUB debugging functionality")

from Linus' tree (in v5.14rc1) interacting with commit

  6c6c1fc09de3 ("modpost: require a MODULE_DESCRIPTION()")

from the kbuild tree.

I have temporarily reverted the latter commit until the former are
fixed up.
