From df77cd10078e36e1b89964e5e8c206add399a98d Mon Sep 17 00:00:00 2001 From: Alex Chiang Date: Mon, 20 Oct 2008 17:41:12 -0600 Subject: [PATCH] PCI: acpiphp: remove 'name' parameter We do not need to manage our own name parameter, especially since the PCI core can change it on our behalf, in the case of duplicate slot names. Remove 'name' from acpiphp's version of struct slot.
