People describe changes as a "fix" all the time for stuff
that isn't an actual fix for a logic defect but is instead
an update to a particular style preference.

Then the "fix" word causes the patch to be rather uselessly
applied to stable trees by AUTOSEL.

It's especially bad when the 'Fixes: <sha1> ("description")'
tag is also added.

It's a difficult thing to regulate and I don't believe a
good mechanism would be possible to add to checkpatch or
coccinelle to help isolate these things.

git diff -w sometimes helps, but that's not really a thing
that checkpatch could do.

Any suggestions?
