This allows drivers to check if a DMA-buf contains a GEM object or not.
Please use an accessor function. I doubt it'll be a fast path.
I think even better if that helper checks against the driver instance too,
since that's really the answer you want drm_prime_try_cast_to_gem_bo or
similar, which will return NULL if it's not a prime dma-buf or not one for
the current driver instance. Feel free to improve the naming :-)
Yeah, agree with that approach.
Additional to that please split this set from the patches which change
the hardware config.
That should make it much easier to review,
Christian.
