From dbbcbb2d95dc4faa3b96d39f78032c85e8745c0c Mon Sep 17 00:00:00 2001 From: Daniel Walker Date: Fri, 28 Mar 2008 14:41:27 -0700 Subject: [PATCH] netdev: ehea: locking order correction Nested locks always need to be taken in the same order. This change factors out the ehea_fw_handles.lock to make the locking order consistent.
