Subject[PATCH 4.9 71/93] drm/nouveau/disp/nv50-: split chid into chid.ctrl and chid.user
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ben Skeggs <bskeggs@redhat.com>

[ Upstream commit 4391d7f5c79a9fe6fa11cf6c160ca7f7bdb49d2a ]

GP102/GP104 make life difficult by redefining the channel indices for
some registers, but not others.
