[PATCH] ppc32: Fix string comparing in platform_notify_map
Fixed odd function behavior when dev->bus_id does not contain '.' - it compared that case 0 characters of the string and hereby reported success and executed callback. Now bus_id's are compared correctly, extra callback triggering eliminated. Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
