Yeah, this is 100% technically correct way of moving things.

The problem is that driver maintainers are usually not quick taking
this type of changes. In my experience, if we merge #1 only, we'll
end up with just another flavor of HIWORD_UPDATE(), maybe adopted
by a couple of drivers.

This is exactly opposite to the original goal of the series: nice and
almost complete consolidation of scattered HIWORD_UPDATE() versions.

So far, there's the only conflict with the others, and Andy said he's
OK to hold his series.

I would prefer to have all those patches in bitmap-for-next for a while.
If there will be more conflicts, then yeah, I'll follow your route.
Otherwise, let's keep things as they are, and encourage developers to
test their patches against linux-next, as they normally should.

Thanks,
Yury
