Subject: tools lib traceevent: Check result of malloc() during reading token
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e54b34aed1c4082ed03f4d1f7a19276059b1e30a;p=linux-beck.git

tools lib traceevent: Check result of malloc() during reading token

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