I would try to add the upstream commit as patch, and call it patch-git_662b6d -- that way it is clear that it comes from upstream and can probably go in the next upgrade.

Also I would keep the whole header of the commit in there.

Merge patches to one file.

If this is a verbatim upstream patch, you could simply add a patch block:

PATCH_SITES=    https://github.com/${GH_ACCOUNT}/${GH_PROJECT}/commit/
PATCHFILES=     662b6db3f3c395b552fa16f7fb22558aa38fe6aa.patch:-p1 \

and run make makesum again.
