Merge series "ASoC: tidyup error message timing" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

Hi Mark

Indicating error message when failed case is very useful for debuging.
In many case, it uses below style.

	int function(...)
	{
		...
		return ret;
	}

	int caller(...)
	{
		...
		ret = function(...);
		if (ret < 0)
			dev_err(...)
		...
	}

This is not so bad, but in this style *each caller* needs to indicate
duplicate same error message, and some caller is forgetting to do it.
And caller can't indicate detail function() error information.

I know many people have many opinion, but if function() indicates error
message, we can get same and detail information without forgot, and it is better.
This patch-set tidyup to do it.

	int function(...)
	{
		...
		if (ret < 0)
			dev_err(...)

		return ret;
	}

	int caller(...)
	{
		...
		ret = function(...);
		...
	}
