1. Would another imperative wording become 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=v6.18-rc6#n94

2. You may occasionally put more than 60 characters into text lines
   of such a change description.

3. Would a summary phrase like “Prevent null pointer dereference
   in intel_th_output_enable()” be more appropriate?
