2023-03-20ASoC: dwc: dwc-i2s: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2022-06-27ASoC: dwc: Migrate to new style legacy DAI naming flagCharles Keepax
Change the legacy DAI naming flag from opting in to the new scheme (non_legacy_dai_naming), to opting out of it (legacy_dai_naming). This driver appears to be on the CPU side of the DAI link and currently uses the legacy naming, so add the new flag.

DAI has playback_active and capture_active to care usage count. OTOH, we have SNDRV_PCM_STREAM_PLAYBACK/CAPTURE. But because of this kind of implementation mismatch, ALSA SoC has many verbose code.

2020-01-21ASoC: dwc: dwc-i2s: move .suspend/.resume to componentKuninori Morimoto
There is no big difference at implementation for .suspend/.resume between DAI driver and Component driver. But because some driver is using DAI version, thus ALSA SoC needs to keep supporting it, hence, framework becoming verbose. If we can switch all DAI driver .suspend/.resume to Component driver, we can remove verbose code from ALSA SoC. Driver is getting its private data via dai->dev. But dai->dev and component->dev are same dev, thus, we can convert these. For same reason, we can convert dai->active to component->active if necessary. This patch moves DAI driver .suspend/.resume to Component driver Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Link: https://lore.kernel.org/r/87y2u3x7iy.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>

2017-04-30ASoC: dwc: Disallow building designware_pcm as a moduleJose Abreu
Designware PCM is an extension to Designware I2S and they are dependent on each other. For this reason, make Designware PCM a boolean which will compile with Desigwnare I2S module. The name of the module is not changed but the name of the files need to be changed. Also, without this commit we get errors when probbing designware_i2s module because of unspecified license: designware_pcm: module license 'unspecified' taints kernel. Disabling lock debugging due to kernel taint designware_pcm: Unknown symbol __rcu_read_lock (err 0) designware_pcm: Unknown symbol devm_snd_soc_register_platform (err 0) designware_pcm: Unknown symbol synchronize_rcu (err 0) designware_pcm: Unknown symbol __rcu_read_unlock (err 0) designware_pcm: Unknown symbol snd_soc_set_runtime_hwparams (err 0) So, this is really needed as a fix.
