Not from my grep.  The ones that don't have space are the ones that don't have
numbers either. Of course we could just ignore this and allow to either have
spaces or not.

git grep -e "Wa[A-Z]" -- drivers/gpu/drm/i915/

vs

git grep -i -e "WA \#" -- drivers/gpu/drm/i915/


... and this last one shows I forgot one case in
drivers/gpu/drm/i915/intel_pm.c
