3.16.55-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Ben Hutchings <ben@xxxxxxxxxxxxxxx> Commit 49e67dd17649 "of: fdt: add missing allocation-failure check" added a "return NULL" statement in __unflatten_device_tree(). When applied to the 3.16-stable branch, this introduced a compiler warning (not an error!) because the function returns void here.
