Subject: [PATCH 13/14] Driver core: Make platform_device_add_data accept a const pointer

From: Scott Wood <scottwood@...escale.com>

platform_device_add_data() makes a copy of the data that is given to it,
and thus the parameter can be const.  This removes a warning when data
from get_property() on powerpc is handed to platform_device_add_data(),
as get_property() returns a const pointer.
