Hmmm, I'm confused why this never happened before :-)

We conditionalize linux/of_device.h inclusion with CONFIG_SPARC64, yet
we unconditionally use "struct of_device *" pointers in the driver
with no such ifdef protection.

Even if we unconditionally included linux/of_device.h, that file does
nothing unless CONFIG_OF_DEVICE is defined so it should have always
produced these warnings since I can't see from where else it could
have gotten even a "struct of_device;" somewhere.

Do you have any idea Randy?  Pease try analyze this further so we can
fix it properly.

THanks!
