When quoting changeset IDs, please do it in the form

  0594ad1a66381076f0fa06f5605ea5023f600586 ("mfd/pcf50633-gpio.c: add MODULE_LICENSE")

There's a good reason for this, but I forget what it is.  Perhaps so
that the same commit can be located if it has a different hash?  I
expect that commits get a different hash when backported into -stable,
for example.

I spend my life making changes like that to changelogs, but when I went
to fix up your 434b5394fd85c212619306cda6bf087be737b35a, I was unable
to locate any commit which has that hash.

<searches for a while>

Ah, you're referring to a -mmotm patch.  The hashes in -mmotm aren't
useful because the tree gets regenerated each time.  So let's refer to
that patch via just its title, "page allocator: replace the
watermark-related union in struct zone with a watermark[] array".
