[PATCH 3.2 121/140] of: fdt: Fix return with value in void function

3.2.100-rc1 review patch. If anyone has any objections, please let me know.

------------------

From: Ben Hutchings ben@decadent.org.uk

Commit 49e67dd17649 "of: fdt: add missing allocation-failure check" added a "return NULL" statement in __unflatten_device_tree(). When applied to the 3.2-stable branch, this introduced a compiler warning (not an error!) because the function returns void here.
