2020-07-23ASoC: soc-xxx: add asoc_substream_to_rtd()Kuninori Morimoto1-6/+6
Current soc-xxx are getting rtd from substream by rtd = substream->private_data; But, getting data from "private_data" is very unclear. This patch adds asoc_substream_to_rtd() macro which is easy to understand that rtd from substream.

2020-06-23ASoC: soc-link: introduce exit() callbackPierre-Louis Bossart1-0/+6
Some machine drivers allocate or request resources with snd_soc_link_init() phase of the card probe. These resources need to be properly released when removing a card, and this patch suggests a dual exit() callback. The exit() is invoked in soc_remove_pcm_runtime(), which is not completely symmetric with the init() invoked in soc_init_pcm_runtime(). Alternate solutions were considered, e.g. adding a .remove() callback for the platform driver, but that's not symmetrical at all and would be difficult to handle if there are more than one dailink implementing an .init(). We looked also into using .remove_dai_link() callback, but that would also be imbalanced. Note that because of the error handling in snd_soc_bind_card(), which jumps to probe_end, there is no way to guarantee the exit() is invoked with resources allocated in the init(). Prior to releasing those resources, implementations of the exit() callback shall check the resources are valid.

2020-05-29ASoC: reduce verbosity of error messages for sof-dai and sof-linkPierre-Louis Bossart1-1/+5
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>
