[Stephen Rothwell]

Hi all,

After merging the drm tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

Caused by commit

  53b2622e7746 ("drm/i915/execlists: Avoid reusing the same logical CCID")

from the drm-intel-fixes tree interacting with commits

  606727842d8b ("drm/i915/gt: Include the execlists CCID of each port in the engine dump")
  4c977837ba29 ("drm/i915/execlists: Peek at the next submission for error interrupts")

from the drm tree.

I have added teh following merge fix patch.
