From acde2d8037f4502669af251e44b05579681e0dc1 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Thu, 29 Mar 2012 20:21:32 +1000 Subject: [PATCH] Revert "drm/nouveau: inform userspace of new kernel subchannel requirements" This reverts commit a81f15499887d3f9f24ec70bb9b7e778942a6b7b. Gah, we have a released userspace component using fixed subc assignment that conflicts with this. To avoid breaking ABI this needs to be reverted.
