Can you *please* use a cover-letter when sending more that a single
patch? I expect there is an overarching motive to this series. Where
is it described?

Also, please look at the way the subject lines are written for most
irqchip patches:

irqchip/foo: Frobify the bar callback return value

Note the capital letter after the ':', and the fact that it starts
with a verb. Here, I would have liked to see:

irqchip/stm32-exti: Fix set_affinity() return value

and leave the meat of the description to the commit log (instead of
saying the exact same thing twice).
</rant>

Thanks,

M.
