We talked about this as late as February this year. It's has been a
long-standing issue that we've struggled with how we should manage.
When I talked to you about it (irqchip drivers at the time), you said
you were in general fine with us merging driver patches when someone
times out waiting on you to review/merge a patch. My concern at the
time is that while we can look at the code of the patch and review
that, we don't have the larger picture of what's going on in the
subsystem. Which is what caused problems here, I'd say.
So, we'll dial back and stop taking these patches through our tree
without an explicit ack or shared branch from you (or Daniel on
clocksource). Not a problem at all.

We obviously never intended to cause any problems like these, and I
apologize for that. On the other hand, it would have been a lot easier
to handle had the code on your end landed a bit sooner than in the
middle of the merge window.

Not much I can say besides what's above and that I owe you a few beers
at the next conference.
