Strangely, my checkpatch invocation on next-20221116 did not show that
warning and I am unaware that I made any specific changes to
checkpatch or its configuration.
Anyway, checkpatch and you, Tommaso, are right and the patch can of
course be improved. I sent out a patch v2:
https://lore.kernel.org/all/20221123075216.28193-1-lukas.bulwahn@xxxxxxxxx/
I hope to get an Acked-by: tag from you now. Thanks.
Lukas
