[PATCH 02/13] bpf tools: Fix syscall argument

From: Arnaldo Carvalho de Melo
Date: Fri Apr 29 2016 - 10:57:54 EST


From: Florian Fainelli <f.fainelli@xxxxxxxxx>

Coverity flagged this under CID 1354884 as a sizeof mismatch, it turns
out that the argument "attr" passed to syscall should have been a
pointer to attr in the first place.
