* ASoC: dwc: Use managed buffer allocationTakashi Iwai2019-12-111-22/+2
| | | | | | | | | | | | Clean up the drivers with the new managed buffer allocation API. The superfluous snd_pcm_lib_malloc_pages() and snd_pcm_lib_free_pages() calls are dropped, as well as the superfluous snd_pcm_lib_preallocate_free_for_all() call. As of the result, hw_free and pcm_destruct ops became empty and got removed.

* ASoC: dwc: Drop superfluous ioctl PCM opsTakashi Iwai2019-12-111-1/+0
| | | | | | | | | ASoC PCM core deals the empty ioctl field now as default. Let's kill the redundant lines. Signed-off-by: Takashi Iwai <tiwai@suse.de> Link: https://lore.kernel.org/r/20191210145406.21419-6-tiwai@suse.de Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: Remove superfluous snd_dma_continuous_data()Takashi Iwai2019-11-091-1/+1
| | | | | | | | | | | | The recent change (commit 08422d2c559d: "ALSA: memalloc: Allow NULL device for SNDRV_DMA_TYPE_CONTINOUS type") made the PCM preallocation helper accepting NULL as the device pointer for the default usage. Drop the snd_dma_continuous_data() usage that became superfluous from the callers.

* ASoC: dwc: dwc-pcm: remove snd_pcm_opsKuninori Morimoto2019-10-081-22/+26
| | | | | | | | | snd_pcm_ops is no longer needed. Let's use component driver callback. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Link: https://lore.kernel.org/r/87h84r90dk.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: dwc: Drop superfluous PCM preallocation error checksTakashi Iwai2019-02-061-1/+2
| | | | | | | | | snd_pcm_lib_preallocate_pages() and co always succeed, so the error check is simply redundant. Drop it. Reviewed-by: Jaroslav Kysela <perex@perex.cz> Acked-by: Mark Brown <broonie@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ASoC: dwc: Disallow building designware_pcm as a moduleJose Abreu2017-04-301-0/+281
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.
