From dfb6b7c109a7f98d324a759599d1b4616f02c79f Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Mon, 23 Sep 2013 04:08:13 +0200 Subject: [PATCH] Revert "rt2x00pci: Use PCI MSIs whenever possible" This reverts commit 9483f40d8d01918b399b4e24d0c1111db0afffeb. Some devices stop to connect with above commit, see: https://bugzilla.kernel.org/show_bug.cgi?id=61621 Since there is no clear benefit of having MSI enabled, just revert change to fix the problem.
