Miller" , Nicolas Pitre Cc: linux-kernel@vger.kernel.org Subject: [PATCH] smc91x: fix unused flags warnings on UP systems Date: Wed, 9 Dec 2009 08:40:04 -0500 Message-Id: <1260366004-27366-1-git-send-email-vapier@gentoo.org> X-Mailer: git-send-email 1.6.5.5 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1366 Lines: 34 Local flags variables will be declared whenever these functions get used, but obviously on UP systems the flags parameter won't be touched. So add some dummy ops that get optimized away anyways to satisfy gcc's warnings.
