Subject: [PATCH 2/2] bfp tools: Fix syscall argument
Date: Sun, 24 Apr 2016 19:34:54 -0700 [thread overview]
Message-ID: <1461551694-5512-3-git-send-email-f.fainelli@gmail.com> (raw)
In-Reply-To: <1461551694-5512-1-git-send-email-f.fainelli@gmail.com>
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.
Reported-by: coverity (CID 1354884)
Fixes: 8f9e05fb298f ("perf tools: Fix PowerPC native building")
