Hi Dave,
Today's linux-next merge of the drm tree got a conflict in
drivers/gpu/drm/vmwgfx/vmwgfx_kms.c between commit e7ac9211f29f ("vmwgfx:
Refactor kms code to use vmw_user_lookup_handle helper") from Linus' tree
and commit 308e5bcbdb10 ("drm: add an fb creation ioctl that takes a
pixel format v5") from the drm tree.
I fixed it up (I think - see below) and can carry the fix as necessary.
Dave, you might like to merge the branch you sent to Linus into your
drm-next branch to fix this up.
