This patch looks good to me.

If you could add a short description of what this PR is about in
the commit's revision log, so as to avoid the need to go through
a PR, which is not always a straightforward (or even concise read),
that would be very good.

In terms of items for submission, we have a checklist:
https://sourceware.org/gdb/wiki/ContributionChecklist

There is a lot of important information there, if you haven't read
it yet.

As far as this patch is concerned, the only bits that are missing
are a period at the end of your sentence in your ChangeLog entry;
and an indication that you ran the testsuite before and after
your patch, showing no regression (this one is unlikely to produce
any, but better safe than sorry) - that indication should be in
the commit's revision log, including the platform that was used
to perform the testing.

Please re-send an updated patch, and I will push it for you.

Thank you!
