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

Hi all,

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


between commits:

  a58555359a9f ("drm/amd/display: Fix DSC not Enabled on Direct MST Sink")
  c29085d29562 ("drm/amd/display: Enable DSC Flag in MST Mode Validation")

from the amdgpu tree and commit:

  7707dd602259 ("drm/dp_mst: Fix fractional DSC bpp handling")

from the drm-intel 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.
