I've found a minor bug and a small improvement.

[PATCH 1/2] devtools: fix check of multiple commits fixed at once

[Thomas Monjalon]

When looking for fixes to backport,
only the first origin commit hash (from "Fixes:") was checked.
There is very little chance that the next commits being fixed
have a wrong hash in the commit log of the fix,
but it is fixed by checking them all before proceeding further.

Fixes: 752d8e097ec1 ("scripts: show fixes with release version of bug")

[PATCH 2/2] devtools: deduplicate function to mark fixes

[Thomas Monjalon]

In the commit 8070d8fecb4e ("devtools: add fixes flag to commit listing")
the function to mark a commit for "stable" was duplicated for "Fixes:" mark.

The code is a bit smaller by using a single function for both marks.
