Since these drivers should also be used for R-Car Gen3, I assume someone will
have to fix the problem in the same way the designware pci driver is being modified.
Please see http://lists.infradead.org/pipermail/linux-arm-kernel/2015-July/353421.html

Of course, as a quick fix for the compile test failure, this is fine.
