Hi all,

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

In file included from include/trace/define_trace.h:102,
                 from drivers/gpu/drm/amd/amdgpu/amdgpu_trace.h:502,

Caused by commit

  2c2fdb8bca29 ("drm/amdgpu: fix amdgpu trace event print string format error")

from the drm tree interacting with commit

  60fdad00827c ("ftrace: Rework event_create_dir()")

from the tip tree.

I have added the following merge fix patch:
