Subject: [PATCH 9/9] tools lib traceevent: Use global 'O' processing code
Date: Thu, 19 Dec 2013 14:42:07 +0100
Message-Id: <1387460527-15030-10-git-send-email-jolsa@redhat.com>
In-Reply-To: <1387460527-15030-1-git-send-email-jolsa@redhat.com>
References: <1387460527-15030-1-git-send-email-jolsa@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

Using global 'O' processing code because it's already
setup due to the scripts/Makefile.include include.

Using global variable OUTPUT instead of the local
BUILD_OUTPUT.
