From 542df5de56a23bf2d94b75e2b304ab0e5a5508a8 Mon Sep 17 00:00:00 2001 From: Rajesh Shah Date: Thu, 28 Apr 2005 00:25:50 -0700 Subject: [PATCH] acpi bridge hotadd: Remove hot-plugged devices that could not be allocated resources When hot-plugging an I/O hierarchy that contains many bridges and leaf devices, it's possible that there are not enough resources to start all the device present. If we fail to assign a resource, clear the corresponding value in the pci_dev structure, so other code can take corrective action.
