From dc731fbbadf5d65c98fcd6c86472aa286c16458a Mon Sep 17 00:00:00 2001 From: Subrata Modak Date: Tue, 21 Jul 2009 08:02:27 +0530 Subject: x86: Work around compilation warning in arch/x86/kernel/apm_32.c The following fix was initially inspired by David Howells fix few days back: http://lkml.org/lkml/2009/7/9/109 However, Ingo disapproves such fixes as it's dangerous (it can hide future, relevant warnings) - in something as performance-uncritical. So, initialize 'err' to '0' to work around a GCC false positive warning: http://lkml.org/lkml/2009/7/18/89 Signed-off-by: Subrata Modak Cc: Sachin P Sant Cc: David Howells Cc: Balbir Singh Cc: Stephen Rothwell LKML-Reference: <20090721023226.31855.67236.sendpatchset@subratamodak.linux.ibm.com> Signed-off-by: Ingo Molnar --- arch/x86/kernel/apm_32.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/x86/kernel/apm_32.c b/arch/x86/kernel/apm_32.c index 79302e9a33a..442b5508893 100644 --- a/arch/x86/kernel/apm_32.c +++ b/arch/x86/kernel/apm_32.c @@ -811,7 +811,7 @@ static int apm_do_idle(void) u8 ret = 0; int idled = 0; int polling; - int err; + int err = 0; polling = !!(current_thread_info()->status & TS_POLLING); if (polling) { -- cgit v1.2.3
