[Freedreno] [PATCH v6 19/19] drm/msm/dpu: add wb_idx to DRM traces in dpu_encoder

Hi Dmitry

Thanks for fixing it up.

I agree about the indentation issue.

And yes even wb_idx missing in TP_ARGS seems like a geniune miss.

But the weird part is it did not break my compilation. I tested even now 
without your fix.

Am I missing something to be enabled in my config to replicate the error 
for future reference?

Thanks

Abhinav
