From fd0775bfc9feb036e6efb669133d644ae29e12b8 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Wed, 9 Dec 2009 03:40:04 +0000 Subject: [PATCH] smc91x: fix unused flags warnings on UP systems 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. Signed-off-by: Mike Frysinger Acked-by: Nicolas Pitre Signed-off-by: David S.
