The advantage is that all mainline patches apply cleanly.  I can prepare
a set without the reverts if you want that, but that would mean a number
of context adjustments in the backport.

I don't think it helps much.  The mainline patch applying the macro to
the drivers cannot be used anyway, as that is a bulk change touching a
large number of drivers at once.  And this part of the driver is rarely
used as context, so it doesn't affect backporting other patches.  Better
just leave it as it is.
