This function call was found to be unnecessary as there is no equivalent
platform_get_drvdata() call to access the private data of the driver. Also,
the private data is defined in this driver, so there is no risk of it being
accessed outside of this driver file.

This entire block could become now:

        return devm_hwrng_register(dev, &trng->rng);

Coming back here.
I wonder if there is a desire to keep the prints above.
If yes, then this is fine as-is.
With that:
