From a56bc69a182f501582557af7fad5bc882b1c856c Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Fri, 14 Sep 2007 15:33:13 +1000 Subject: PCI: Fix incorrect argument order to list_add_tail() in PCI dynamic ID code The code for dynamically assigning new ids to PCI drivers, store_new_id(), calls list_add_tail() with the list head and new node arguments in reversed order. The result is that every new id written essentially overwrites the previous list of ids.
