From 6fdfa97073a2bcbb60d900654c612b2ff09b9cb7 Mon Sep 17 00:00:00 2001 From: Scott Feldman Date: Thu, 3 Sep 2009 17:02:45 +0000 Subject: enic: organize device initialization/deinit into separate functions To unclutter probe() a little bit, put all device initialization code in one spot and device deinit code in another spot. Also remove unused rq->buf_index variable/func. Signed-off-by: Scott Feldman Signed-off-by: David S.
