From 3594f4c0d7bc51e3a7e6d73c44e368ae079e42f3 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Thu, 6 Jun 2013 13:52:21 -0700 Subject: [PATCH] charger-manager: Ensure event is not used as format string The exposed interface for cm_notify_event() could result in the event msg string being parsed as a format string. Make sure it is only used as a literal string.
