I don't think we should polute the kernel log buffers with this. Maybe a
DRM_DEBUG() if you really want to get some notification?

I agree with you completely. I think we should use DRM_DEBUG_KMS()
like intel_framebuffer_init() uses to log unsupported formats and
modifiers.
I will send a v2 patch for this.
