<pre>I first tried patch with options --dry-run -p1 -i and got the following :-
checking file drivers/gpu/drm/i915/intel_engine_cs.c
checking file drivers/gpu/drm/i915/intel_ringbuffer.c
Hunk #1 succeeded at 1357 (offset -4 lines).
Hunk #2 FAILED at 1389.
Hunk #3 succeeded at 1427 with fuzz 1 (offset -29 lines).
Hunk #4 FAILED at 1658.
Hunk #5 succeeded at 2128 (offset -50 lines).
2 out of 5 hunks FAILED
checking file drivers/gpu/drm/i915/intel_ringbuffer.h
Hunk #1 succeeded at 865 (offset -4 lines).
So I assume the patch is for a different base version of intel_ringbuffer.c</pre>
