OK, this is a bit strange.

I can see that Greg's 737a3bb9416ce2a7c7a4170852473a4fcc9 would cause
radeon_cp_init() to crash when it is called via ioctl.  It calls
platform_device_register_resndata(), but platform_device_register_resndata()
got unloaded from kernel memory.

But that will only happen if CONFIG_MODULES=n, and in the config attached to
the gentto report, CONFIG_MODULES=y.  So platform_device_register_resndata()
won't have been unloaded!

Still, we should revert 737a3bb9416ce2a7c7a4170852473a4fcc9, as its assumptions
are wrong in this case.
