From 0c62fc6dd02c8d793c75ae76a9b6881fc36388ad Mon Sep 17 00:00:00 2001 From: Nelson Elhage Date: Wed, 8 Dec 2010 10:13:55 -0800 Subject: [PATCH] econet: Do the correct cleanup after an unprivileged SIOCSIFADDR. We need to drop the mutex and do a dev_put, so set an error code and break like the other paths, instead of returning directly. Signed-off-by: Nelson Elhage Signed-off-by: David S.
