[PATCH 4.4 16/70] kbuild: clang: Disable address-of-packed-member warning

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Matthias Kaehlcke <mka@xxxxxxxxxxxx>

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.
