From 0dad3510ee82bcf8a380b81a2184a664a911ef9c Mon Sep 17 00:00:00 2001 From: Satoru Takeuchi Date: Tue, 12 Sep 2006 10:17:46 -0700 Subject: [PATCH] acpiphp: stop bus device before acpi_bus_trim Contrary to PCI bridge hot-add, we need to follow the sequence below for PCI bridge hot-removal. (1) Stop devices (detach drivers, remove from the global list, etc.) (2) Unbind ACPI node from the devices (remove the _PRT entries) (3) Remove devices (remove from the device list, etc.) This patch fixes acpiphp driver to follow above sequence for P2P bridge hot-removal.
