There are no users of OF_NO_DEEP_PROBE, and of_match_node() now gracefully handles being passed a NULL pointer, so the checks at the top of of_platform_bus_probe can be dropped. While at it, consolidate the root node pointer check to be easier to read and tidy up related comments. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
