Recent changes result in multiple dmesg traces such as: [ 14.410435] Audio Port: ASoC: error at snd_soc_link_startup on Audio Port: 1 [ 14.410446] sst-mfld-platform sst-mfld-platform: ASoC: error at snd_soc_dai_startup on media-cpu-dai: 1 These messages are not really errors, when dai and dai-link callbacks return the value of e.g. snd_pcm_hw_constraint_single() the result is "Positive if the value is changed, zero if it's not changed, or a negative error code" Add a simple test to skip the checks for positive returned values Suggested-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Link: https://lore.kernel.org/r/20200529123613.13447-1-pierre-louis.bossart@linux.intel.com Signed-off-by: Mark Brown <broonie@kernel.org>
