Hi all,

After merging the clk tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

5776526beb95 ("clk: Add KUnit tests for clk fixed rate basic type")
5c9dd72d8385 ("of: Add a KUnit test for overlays and test managed APIs")
(and maybe more from the clk tree)

presumably interacting with commit

from the kbuild tree.
