I totally understand your sentiment. I am just the messenger here.

Without the "commit" this patch triggers a loud:

ERROR: Please use git commit description style 'commit <12+ chars of sha1> ("<title line>")' - ie: 'commit 92bd5a139033 ("x86/resctrl: Add interface to write mbm_total_bytes_config")'
#15:
  92bd5a139033 ("x86/resctrl: Add interface to write mbm_total_bytes_config")

I usually (unless, for example, following checkpatch.pl advice causes a change
to fall out of place with surrounding code) try to format my patches to get a
clean slate from checkpatch.pl with the goal to eliminate obstacles to the
patch getting included.
Since you are the one that decides the rules for inclusion you can make this
check to be one where checkpatch.pl can be ignored. No objection from me if
you choose to do so (and I will note the precedent for future patches).
