  It must either fix a real bug that bothers people or just add a
  device ID.

Does this really bother people? Have we seen bug reports?

There is another aspect to this. We are adding warnings saying that
the device tree blob is broken. That should encourage users to upgrade
their device tree blob. But most won't find any newer version. If this
goes into net-next, the roll out will be a lot slower, developers on
the leading edge will find the DT issue and submit a DT patch. By the
time this is in a distro kernel, maybe most of the DT issues will
already be fixed?
