Subject: [PATCH] oprofile, arm: initialize perf_event pointers with NULL
Date: Mon, 30 Aug 2010 18:21:55 +0200 [thread overview]
Message-ID: <mailman.215.1283252618.27306.linux-arm-kernel@lists.infradead.org> (raw)
The pointers must be NULL'ed to avoid double-freeing the pointers in
rare cases during reinitialization.
