I disagree.

checkpatch should handle the default input of patches
as best it can.

I suppose checkpatch could have a different "--input=git"
or some such to avoid certain things that git might produce
that a patch would not.

Deleting useful checks for patches isn't a good idea.

So what?

It would also be too late to do anything about
it anyway as it would already be committed.

I tried it.  It works for me.
What about it doesn't work for you?
