Hi Rob, Matthias,

I needed to resort to remove module build support for the new ringacc UDMA
drivers (now they are in next-20200122) due to the fact that of_msi_get_domain()
is not having the EXPORT_SYMBOL_GPL() which is used by both drivers.

I have found this old patch in lkml, but can not see the history of why it is
not applied.

Regards,
Peter
