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

Hi all,

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

  drivers/gpu/drm/i915/intel_dp.c
  drivers/gpu/drm/i915/intel_drv.h

between commits:

  e845f099f1c6 ("drm/i915/dsc: Add Per connector debugfs node for DSC support/enable")
  f6bff60e927b ("drm/i915/icl: Fix HPD handling for TypeC legacy ports")

from the drm-intel tree and commit:

  96550555a78c ("drm/i915: Pass down rc in intel_encoder->compute_config()")

from the drm-misc 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.

Cheers,
