[PATCH] ASoC: amd: Fix reference to PCM buffer address
by Meng Tang 16 Mar '22

16 Mar '22

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 driver needs to refer to substream->runtime->dma_addr instead for the buffer address.

[PATCH] ASoC: mediatek: mt8195: Fix error handling in mt8195_mt6359_rt1019_rt5682_dev_probe
by Miaoqian Lin 16 Mar '22

The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done. This function only calls of_node_put() in the regular path.

[PATCH] ASoC: sti: Fix deadlock via snd_pcm_stop_xrun() call
by Takashi Iwai 16 Mar '22

16 Mar '22

This is essentially a revert of the commit dc865fb9e7c2 ("ASoC: sti: Use snd_pcm_stop_xrun() helper"), which converted the manual snd_pcm_stop() calls with snd_pcm_stop_xrun(). The commit above introduced a deadlock as snd_pcm_stop_xrun() itself takes the PCM stream lock while the caller already holds it. Since the conversion was done only for consistency reason and the open-call with snd_pcm_stop() to the XRUN state is a correct usage, let's revert the commit back as the fix.
