From 533763d34862101090f8563aa9da202583b2423d Mon Sep 17 00:00:00 2001 From: Martin Gebert Date: Wed, 23 Jul 2008 09:40:09 +0200 Subject: [PATCH] [netdrvr] au1000_eth: Spinlock initialisation fix Seems like the spinlock for the AU1x00 ethernet device is initialised too late, as it is already used in enable_mac(), which is called via mii_probe() before the init takes place. The attached patch is working here for a Linux Au1100 2.6.22.6 kernel, and as far as I checked should also be applicable to the current head (just line numbers differ).
