Author: eri Date: Thu Jul 9 16:28:36 2015 New Revision: 285325 URL: https://svnweb.freebsd.org/changeset/base/285325
Log: Correct issue presented in r285051, apparently neither clang nor gcc complain about this. But clang intis the var to NULL correctly while gcc on at least mips does not. Correct the undefined behavior by initializing the variable properly.
