Subject: [PATCH 13/20] tools lib traceevent: Check result of malloc() during reading token
Date: Thu,  5 Jul 2012 12:45:11 -0300	[thread overview]
Message-ID: <1341503118-13198-14-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1341503118-13198-1-git-send-email-acme@infradead.org>

From: Namhyung Kim <namhyung.kim@lge.com>

The malloc can fail so the return value should be checked.  For now,
just use malloc_or_die().
