Ah!  Nice!

Bjorn was looking recently at struct keystone_pcie and suggested that
perhaps things such as for example the legacy_host_irqs member could be
refactored - in this particular case it seems to only store a single
item in the array, etc.

And this series of patches I found is refactoring a lot of the elements
of the driver and thus the struct keystone_pcie too in due process.

I suppose, it would be just better to wait for you to complete all the
work you have planned?  What do you think?
