Shouldn't this be an error? Or perhaps WARN()? To make sure this gets
noticed since it's obviously a mistake. I'm wondering if perhaps we
could simply remove this check and let the kernel crash if it isn't a
valid function pointer. Is there a case where this not being set at
this point is even possible (or valid?). If not, perhaps it would be
better to just call the SoC generation versions of this function from
here directly rather than going through a function pointer?
