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

Change the DRM traces to include both the intf_mode and wb_idx similar to the DRM prints in the previous change.

This commit got traces broken. I'm going to apply a fix.
