[PATCH] ASoC: Intel: Handle device properties with software node API

[Pierre-Louis Bossart]

Hi Heikki,
Going back to this initial patch, I have a doubt based on Andy Shevchenko's comment on an update [1]

> The function device_add_properties() is going to be removed.
> Replacing it with software node API equivalents.

The replacement pattern takes this one line:

> -	ret = device_add_properties(sdw_dev, props);

which gets replaced by

> +	fwnode = fwnode_create_software_node(props, NULL);
> +	if (IS_ERR(fwnode)) {
> +		return PTR_ERR(fwnode);
>  	}
>  
> +	ret = device_add_software_node(sdw_dev, to_software_node(fwnode));
> +
> +	fwnode_handle_put(fwnode);

is the fwnode_handle_put() actually required here? This seems to work fine in our tests but I wasn't able to find in the code a matching _get().

Thanks for any pointers/comments!
