[PATCH v6 1/3] drm/i915: enum transcoder and pipe are moved into i915_drm.h

[Winkler, Tomas]

Don't you need to name space those definitions in the global space, I guess there are a lot of 'pipe' variables and definitions you can conflict with. 
I guess it should be enum i915_pipe, etc. 

Thanks
Tomas
