From e903fbd41e9a723da194e91816bfb69d442eb116 Mon Sep 17 00:00:00 2001 From: Reinette Chatre Date: Wed, 30 Jan 2008 22:05:15 -0800 Subject: [PATCH] iwlwifi: fix merge sequence: exit on error before state change The intention behind the original patch: "iwlwifi: fix possible read attempt on ucode that is not available" was to exit before any state is changed. Due to its submission directly to 2.6.24 it was not clear how this relates to the latest iwlwifi work. This patch does exactly the same as the previous patch, just earlier to prevent any state from being changed if there is an error. Signed-off-by: Reinette Chatre Signed-off-by: John W.
