From 20e1129ab831486c811d50d3905343ad48c4275f Mon Sep 17 00:00:00 2001 From: David Howells Date: Sun, 30 Oct 2005 15:02:44 -0800 Subject: [PATCH] [PATCH] Keys: Get rid of warning in kmod.c if keys disabled The attached patch gets rid of a "statement without effect" warning when CONFIG_KEYS is disabled by making use of the return value of key_get(). The compiler will optimise all of this away when keys are disabled.
