This list used was by only two platforms with all other platforms defining an own list of valid bus id's to pass to of_platform_bus_probe. This patch: i) copies the default list to the two platforms that depended on it (powerpc) ii) remove the usage of of_default_bus_ids in of_platform_bus_probe iii) removes the definition of the list from all architectures that defined it Passing a NULL 'matches' parameter to of_platform_bus_probe is still valid; the function returns no error in that case as the NULL value is equivalent to an empty list. Signed-off-by: Jonas Bonn <jonas@southpole.se> [grant.likely@secretlab.ca: added __initdata annotations, warn on and return error on missing match table, and fix whitespace errors] Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
