3.2.72-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: David Daney <david.daney@xxxxxxxxxx> commit 3a496b00b6f90c41bd21a410871dfc97d4f3c7ab upstream. If the internal call to of_address_to_resource() fails, we end up looping forever in of_find_matching_node_by_address(). This can be caused by a defective device tree, or calling with an incorrect matches argument. Fix by calling of_find_matching_node() unconditionally at the end of the loop.
