From 16f4f5f0dc33698b841bce71cbc0dd991935b7e1 Mon Sep 17 00:00:00 2001
From: Hans de Goede <hdegoede@redhat.com>

Subject: [PATCH] nv46: Change mc subdev oclass from nv44 to nv4c
MSI interrupts appear to not work for nv46 based cards. Change the mc
subdev oclass for these cards from nv44 to nv4c, the nv4c mc code is
identical to the nv44 mc code except that it does not use msi
(it does not define a msi_rearm callback).
