I think this was standalone and hadn't seen any response from MTD, so I
vacuumed it up like I usually do.

There's no clear pattern amongst subsystem maintainers, and given that I
make a final pass towards the end of the -rc5 week, I will usually look
at what patches haven't been picked up yet and apply them, provided that
they have a Reviewed-by/Acked-by from a DT maintainer.

In this case I missed Mark's reply since it was posted to the cover
letter and therefore didn't show up in Patchwork (I don't know if newer
versions of patchwork track this somehow, the instance on ozlabs
certainly doesn't). I'll work on a way to better track this.

Sometimes I forget to send out acknowledgements. I haven't found a good
and reliable way to automate this.

As I explained earlier, I usually do exactly that, except that I keep
the branch separate and pull the dt-bindings branch into the DTS branch
as a dependency. I might have missed the dependency this time.

Same as for the MTD patch, there were no related DTS or driver changes,
and there was no message that this was applied, so I picked it up while
I was going over the list of pending patches.
