patch file

The makedevs program assigns "ret", but never reads from it.  (It always returns 0.)  While using gcc 4.6.0 for an OMAP target, I got an unused-but-set warning on "ret", which coupled with a -Werror that was set somewhere, bringing the buildroot compile to a halt.  So I have attached a patch that tests "ret", and prints out a warning if there were any failures.
