While it's also unexpected, it's really *duplicated* word.

The above is just duplication of the patch itself, and completely
unnecessary.

The patch subject prefix should be something like "drm/i915:" or
"drm/i915/reg:".

Pro-tip for figuring out good guesses of what the subject prefix should
be:

$ git log --since={5-year} --no-merges --pretty=format:%s -- drivers/gpu/drm/i915/i915_reg.h | sed 's/:.*//' | sort | uniq -c | sort -rn | head
    312 drm/i915
    113 drm/i915/icl
     57 drm/i915/tgl
     26 drm/i915/cnl
     25 drm/i915/display
     22 drm/i915/dg2
     16 drm/i915/psr
     14 drm/i915/gt
     14 drm/i915/adl_p
     12 drm/i915/dg1

The patch itself is fine, but I'm nitpicking on the commit message
because I've seen lots of patches like this, with the same kind of stuff
in the commit messages.

BR,
Jani.
