platform_device_add_data() makes a copy of the data that is given to it,

from get_property() on powerpc is handed to platform_device_add_data(),

Doesn't this cause a compile warning in platform.c, concerning assigning
'data' to struct device's non-const 'platform_data' pointer?

No, because it doesn't assign data to platform_data; it memcpy()s it (as stated above).
