ASoC: samsung: idma: Check of ioremap return value

2022-01-27T07:46:16+00:00

[ Upstream commit 3ecb46755eb85456b459a1a9f952c52986bce8ec ] Because of the potential failure of the ioremap(), the buf->area could be NULL. Therefore, we need to check it and return -ENOMEM in order to transfer the error.

ASoC: topology: Add missing rwsem around snd_ctl_remove() calls

2021-12-08T07:44:05+00:00

[ Upstream commit 7e567b5ae06315ef2d70666b149962e2bb4b97af ] snd_ctl_remove() has to be called with card->controls_rwsem held (when called after the card instantiation).

ASoC: DAPM: Cover regression by kctl change notification fix

2021-11-26T10:58:45+00:00

commit 827b0913a9d9d07a0c3e559dbb20ca4d6d285a54 upstream. The recent fix for DAPM to correct the kctl change notification by the commit 5af82c81b2c4 ("ASoC: DAPM: Fix missing kctl change notifications") caused other regressions since it changed the behavior of snd_soc_dapm_set_pin() that is called from several API functions. Formerly it returned always 0 for success, but now it returns 0 or 1. This patch addresses it, restoring the old behavior of snd_soc_dapm_set_pin() while keeping the fix in snd_soc_dapm_put_pin_switch().

ASoC: DAPM: Fix missing kctl change notifications

2021-10-27T07:32:40+00:00

commit 5af82c81b2c49cfb1cad84d9eb6eab0e3d1c4842 upstream. The put callback of a kcontrol is supposed to return 1 when the value is changed, and this will be notified to user-space. However, some DAPM kcontrols always return 0 (except for errors), hence the user-space misses the update of a control value. This patch corrects the behavior by properly returning 1 when the value gets updated.

ASoC: intel: atom: Fix breakage for PCM buffer address setup

2021-08-26T12:37:54+00:00

[ Upstream commit 65ca89c2b12cca0d473f3dd54267568ad3af55cc ] The commit 2e6b836312a4 ("ASoC: intel: atom: Fix reference to PCM buffer address") changed the reference of PCM buffer address to substream->runtime->dma_addr as the buffer address may change dynamically. However, I forgot that the dma_addr field is still not set up for the CONTINUOUS buffer type (that this driver uses) yet in 5.14 and earlier kernels, and it resulted in garbage I/O. The problem will be fixed in 5.15, but we need to address it quickly for now. The fix is to deduce the address again from the DMA pointer with virt_to_phys(), but from the right one, substream->runtime->dma_area.

ASoC: intel: atom: Fix reference to PCM buffer address

2021-08-26T12:37:43+00:00

commit 2e6b836312a477d647a7920b56810a5a25f6c856 upstream. PCM buffers might be allocated dynamically when the buffer preallocation failed or a larger buffer is requested, and it's not guaranteed that substream->dma_buffer points to the actually used buffer. The address should be retrieved from runtime->dma_addr, instead of substream->dma_buffer (and shouldn't use virt_to_phys). Also, remove the line overriding runtime->dma_area superfluously, which was already set up at the PCM buffer allocation.

ASoC: tegra: Set driver_name=tegra for all machine drivers

2021-07-20T14:22:39+00:00

commit f6eb84fa596abf28959fc7e0b626f925eb1196c7 upstream. The driver_name="tegra" is now required by the newer ALSA UCMs, otherwise Tegra UCMs don't match by the path/name. All Tegra machine drivers are specifying the card's name, but it has no effect if model name is specified in the device-tree since it overrides the card's name. We need to set the driver_name to "tegra" in order to get a usable lookup path for the updated ALSA UCMs. The new UCM lookup path has a form of driver_name/card_name. The old lookup paths that are based on driver module name continue to work as before. Note that UCM matching never worked for Tegra ASoC drivers if they were compiled as built-in, this is fixed by supporting the new naming scheme.
