From 98bd8d05ea5798ff3179ee33f0ca2789722ecc5a Mon Sep 17 00:00:00 2001 From: Chen Gang Date: Wed, 3 Jul 2013 15:04:53 -0700 Subject: arch/frv/kernel/setup.c: use strncmp() instead of memcmp() 'cmdline' is a NUL terminated string, when its length < 4, memcmp() will cause memory access out of boundary. So use strncmp() instead of memcmp().
