Subject: linux-next: manual merge of the drm-misc tree with Linus' tree

From: Stephen Rothwell <[email-masked]>

Hi all,

Today's linux-next merge of the drm-misc tree got a conflict in:

  drivers/gpu/drm/nouveau/nv50_display.c

between commit:

  4a5431af19bc ("drm/nouveau/kms/nv50: update vblank state in response to modeset actions")

from Linus' tree and commit:

  3c847d6cdadb ("drm/nouveau: Convert nouveau to use new iterator macros, v2.")

from the drm-misc tree.

I fixed it up (I think - see below) and can carry the fix as necessary.
This is now fixed as far as linux-next is concerned, but any non
trivial conflicts should be mentioned to your upstream maintainer when
your tree is submitted for merging.  You may also want to consider
cooperating with the maintainer of the conflicting tree to minimise any
particularly complex conflicts.
