Embedding net_device into structures prohibits the usage of flexible arrays in the net_device structure. For more details, see the discussion at [1]. Un-embed the net_device from struct ath10k by converting it into a pointer. Then use the leverage alloc_netdev() to allocate the net_device object at ath10k_core_create(). The free of the device occurs at ath10k_core_destroy().
