From 1f8081f539a80c3d36a17ecd094d104eae60c01c Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Tue, 26 Aug 2008 16:04:05 +0200 Subject: [ARM] mv78xx0: wire up ethernet error interrupt Wire up the ethernet port's error interrupt so that the mv643xx_eth driver can sleep for SMI event completion instead of having to busy-wait for it.
