Will another imperative wording approach become more helpful for an improved
change description?
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?h=v6.17#n94

Can a summary phrase like “Prevent null pointer dereference in brcmf_acpi_probe()”
be nicer?
