From 52ce3e9a7db754b78cf2cbabc87013f921b25b28 Mon Sep 17 00:00:00 2001 From: Zhu Yi Date: Wed, 2 Dec 2009 14:24:37 +0800 Subject: [PATCH] ipw2100: fix rebooting hang with driver loaded Add PCI .shutdown method so that we can disable the device during shutdown or reboot. Without this, the reboot doesn't work well on some platforms. This fixes http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2124 Tested-by: pablo Signed-off-by: Zhu Yi Signed-off-by: John W.
