The issue I have this is that it makes two (or more) things that were
independent now dependent. What about just moving the module_init/
exit() functions into files that are built separately. For the ehci-
fsl case it was trivial, need to look at ehci-pci case.
Ok, my idea required exporting things I didn't really want to
export, so
what about something like this or where you thinking of some more
sophisticated?
If this is good, I'll do the same for ohci.
David, any comments?
