If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Hans de Goede commit 0a363e85cdafbceeee6a49b91c604d0d4d070dc7 upstream. 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).
