The recent addition of __deprecated to the declarations for find_devices etc. produces a whole pile of warnings from the ppc32 code. Since those functions still work perfectly well on ppc32, which doesn't have hotplug support for anything in the OF device tree, and we don't have time to fix that code now, remove the __deprecated markings for now.
