Actually this topic branch doesn't compile:

../drivers/gpu/drm/i915/intel_gvt_mmio_table.c:7:10: fatal error: 'display/intel_dmc_regs.h' file not found
#include "display/intel_dmc_regs.h"
         ^~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.

:( :(

This is the merge conflict that was mentioned. This topic branch needs
to delete the above intel_dmc_regs.h include file

When drm-intel-next merges this PR then need to add it back as part of
the merge resolution - so explain this in the PR text above and
include a diff that does it when you send it again. (or do the merge
yourself as I showed before, it depends on what drm-intel-next wants)
