I do still see this function used in next-20191108 in drivers/soc/.

I'll be happy to adjust my RFC driver if someone points me to how!

Given the current struct layout, a type cast might work (but ugly).
Or if we stay with my current RFC driver design, we could use the
platform_device instead of the soc_device (which would clutter the
screen more than "soc soc0:") or resort to pr_info() w/o device.

Thanks,
Andreas
