From 8239def1b56e0c0c8e0fd3754a12df3d60a64ed7 Mon Sep 17 00:00:00 2001 From: "rajesh.shah@intel.com" Date: Mon, 31 Oct 2005 16:20:13 -0800 Subject: [PATCH] [PATCH] pciehp: fix handling of power faults during hotplug The current pciehp implementation reports a power-fail error even if the condition has cleared by the time the corresponding interrupt handling code gets a chance to run. This patch fixes this problem.
