From d65eba6a7a769bb939303969267cbf1c916358f5 Mon Sep 17 00:00:00 2001 From: Yijing Wang Date: Fri, 12 Apr 2013 05:44:17 +0000 Subject: [PATCH] PCI: acpiphp: Use list_for_each_entry_safe() in acpiphp_sanitize_bus() Function acpiphp_sanitize_bus() may call pci_stop_and_remove_bus_device(), which in turn may remove device from bus->devices list. So walk the bus->devices list with list_for_each_entry_safe(). Signed-off-by: Yijing Wang Signed-off-by: Jiang Liu Signed-off-by: Bjorn Helgaas Reviewed-by: Yinghai Lu Cc: "Rafael J.
