This caused a compile error when using bcma as module:
ERROR: "of_default_bus_match_table" [drivers/bcma/bcma.ko] undefined!

There are two options I guess:
1) Export of_default_bus_match_table
2) Use some better condition like
if (IS_BUILTIN(CONFIG_BCMA) && bus->host_pdev)

Unfortunately I'm on my long holidays right now.

Hauke: do you think you can find a moment to handle this?

I can cook up a patch which uses IS_BUILTIN() so that we get the build
working again. You can fix this better once you come back.

Sorry for the problem :|

No worries, enjoy your vacation :)
