ASoC: soc-dapm.c: tidyup error handling on snd_soc_dapm_add_route()

Browse Source 
Current error handling on snd_soc_dapm_add_route() has some wastes.
It indicates *own* error message *only* for sink or source,
and return error directly at (A). OTOH, it has similar error message at
(B) which indicates *both* sink/source.

And more, (A) is using dev_err(), (B) is using dev_warn().
(B) is caring prefix, but (A) is not.

(X)	int snd_soc_dapm_add_route(...)
	{
		...
		if (wsource == NULL) {
(A)			dev_err(...);
			return -ENODEV;
		}
		if (wsink == NULL) {
(A)			dev_err(...);
			return -ENODEV;
		}

		...

		ret = snd_soc_dapm_add_path(...);
		if (ret)
(B)			goto err;

		return 0;
	err:
(B)		dev_warn(...);
		return ret;
	}

Above snd_soc_dapm_add_route() (= X) is called from
snd_soc_dapm_add_routes() (= Y).
(X) will indicate error message by itself, but (Y) will indicate
own error message at (C). (C) is duplicated.

(Y)	int snd_soc_dapm_add_routes(...)
	{
		...
		for (...) {
(X)			int r = snd_soc_dapm_add_route(...);
			if (r < 0) {
(C)				dev_err(...);
				ret = r;
			}
			...
		}
		...
	}

This patch (1) merges these error message (= A,B) into one,
(2) use dev_err(), (3) remove duplicate error message (= C) from
snd_soc_dapm_add_routes().

By this patch, it will indicate error message like this.

	- error message with prefix
	- not found widget will have "(*)" mark
	- it indicates [control] if exists.

ex)
[if no sink with control]

	ASoC: Failed to add route SOURCE -> [CTRL] -> SINK(*)

[if no source without control]

	ASoC: Failed to add route SOURCE(*) -> SINK
