ASoC: soc-pcm: indicate error message at soc_pcm_hw_params()
Indicating error message when failed case is very useful for debuging. In many case, its style is like below. 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. If function() indicates error message, we can get same and detail information without forgot. int function(...) { ... if (ret < 0) dev_err(...) return ret; } int caller(...) { ... ret = function(...); ... } This patch follow above style at soc_pcm_hw_params(). By this patch, dpcm_fe/be_dai_hw_params(...) temporary lacks FE/BE error info, but it will reborn soon.
