Subject: [PATCH 4.9 25/59] kbuild: clang: Disable address-of-packed-member warning
Date: Wed, 21 Nov 2018 20:06:40 +0100 [thread overview]
Message-ID: <20181121183509.250636581@linuxfoundation.org> (raw)
In-Reply-To: <20181121183508.262873520@linuxfoundation.org>
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthias Kaehlcke <mka@chromium.org>
commit bfb38988c51e440fd7062ddf3157f7d8b1dd5d70 upstream.
clang generates plenty of these warnings in different parts of the code,
to an extent that the warnings are little more than noise. Disable the
'address-of-packed-member' warning.
