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<subrata@linux.vnet.ibm.com> Cc: Sachin P Sant <sachinp@linux.vnet.ibm.com> Cc: David Howells <dhowells@redhat.com> Cc: Balbir Singh <balbir@linux.vnet.ibm.com> Cc: Stephen Rothwell <sfr@canb.auug.org.au> LKML-Reference: <20090721023226.31855.67236.sendpatchset@subratamodak.linux.ibm.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
