Let's add more folks who were involved in

1b477f42285e ("drm/nouveau/kms: Add INHERIT ioctl to nvkm/nvif for reading
IOR state")

Apparently, someone wants to know that the loop over the crtcs in
nv50_display_read_hw_or_state() didn't find a head.

Holler if you need me to run a debug patch to figure out why.

We're getting close to releasing so I guess we either debug this or shut
up the WARN.

Thx.
