I noticed another commit with the questionable subject
“pinctrl:sunplus: Add check for kmalloc”.
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/pinctrl/sunplus/sppctl.c?h=next-20230613&id=73f8ce7f961afcb3be49352efeb7c26cc1c00cc4

I find such a commit message inappropriate for the applied
source code adjustment.

Markus
