stm32_hash_remove() is only called after stm32_hash_probe() succeeded. In this case platform_set_drvdata() was called with a non-NULL data patameter. The check for hdev being non-NULL can be dropped because hdev is never NULL (or something bad like memory corruption happened and then the check doesn't help any more either).
