Hmm. Did you pass in 'origin' to git request-pull too?

No, that's only necessary for when the branch has merges and can have
multiple merge bases as a result - that will make 'git diff' unable to
find an unambiguous place to start the diff from (see
Documentation/maintainer/messy-diffstat.rst for the details).

But your tree doesn't have that issue, and you can also see the old
commits in your shortlog (and the "messy diffstat" is _only_ about the
diff, not about the commit list). And you can see the same effect in
the shortlog, ie I merged your earlier fixes pull request  in commit
9be9ed2612b5 ("Merge tag 'platform-drivers-x86-v5.18-4' of
git://..."), and it already had

    * tag 'platform-drivers-x86-v5.18-4' of
git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/pla>
      platform/surface: aggregator: Fix initialization order when
compiling as builtin module
      platform/surface: gpe: Add support for Surface Pro 8
      platform/x86/intel: Fix 'rmmod pmt_telemetry' panic
      platform/x86: thinkpad_acpi: Correct dual fan probe
      platform/x86: thinkpad_acpi: Add a s2idle resume quirk for a
number of laptops
      platform/x86: thinkpad_acpi: Convert btusb DMI list to quirks

but notice how your pll request had those commits listed again (ie it
had, for example:

  Maximilian Luz (2):
        platform/surface: gpe: Add support for Surface Pro 8
        platform/surface: aggregator: Fix initialization order when
compiling as builtin module

in there).

And while merges can confuse the diffstat, the actual commit list
doesn't care: it does a proper set operation, and having multiple
merge bases doesn't matter.

This all is not a huge deal - I figured out what was going on, so it
wasn't a problem.

I just mentioned it because that whole "Linus figures it out" does
take some time and effort, and I'm really really lazy and much prefer
to just do the pull and look at the result and go "Yeah, looks good"
and go on to the next one...

Thanks,
                 Linus
