From 6ef6f0e33c4645fc8d23201ad5a6a289b4303cbb Mon Sep 17 00:00:00 2001 From: Rajesh Shah Date: Thu, 28 Apr 2005 00:25:49 -0700 Subject: [PATCH] acpi bridge hotadd: Link newly created pci child bus to its parent on creation When a pci child bus is created, add it to the parent's children list immediately rather than waiting till pci_bus_add_devices(). For hot-plug bridges/devices, pci_bus_add_devices() may be called much later, after they have been properly configured. In the meantime, this allows us to use the normal pci bus search functions for the hot-plug bridges/buses.
