Subject: linux-next: manual merge of the driver-core tree with the drm tree

Hi all,

Today's linux-next merge of the driver-core tree got a conflict in:

  drivers/gpu/drm/Kconfig

between commits:

  ba8f16cd08190 ("drm: selftest: convert drm_damage_helper selftest to KUnit")
  fc8d29e298cf4 ("drm: selftest: convert drm_mm selftest to KUnit")

from the drm tree and commit:

  84ec67288c10f ("drm_print: wrap drm_*_dbg in dyndbg descriptor factory macro")

from the driver-core tree.

I fixed it up (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.
