From 3a83ad12b850c3c5b89fa9008bdd0c0782f0cf68 Mon Sep 17 00:00:00 2001 From: Hayes Wang Date: Wed, 11 Jul 2012 20:31:56 +0800 Subject: [PATCH] r8169: remove rtl_ocpdr_cond. It is not needed for mac_ocp_{write / read}. Actually bit 31 of OCPDR does not change and r8168_mac_ocp_read always returns ~0.
