ASoC: SOF: stream-ipc: Check for cstream nullity in sof_ipc_msg_data()

2026-06-01T15:39:31+00:00

[ Upstream commit d8d99c3b5c485f339864aeaa29f76269cc0ea975 ] The nullity of sps->cstream should be checked similarly as it is done in sof_set_stream_data_offset() function. Assuming that it is not NULL if sps->stream is NULL is incorrect and can lead to NULL pointer dereference.

ASoC: SOF: pcm: Clear the susbstream pointer to NULL on close

2026-06-01T15:39:31+00:00

[ Upstream commit 46c7b901e2a03536df5a3cb40b3b26e2be505df6 ] The spcm->stream[substream->stream].substream is set during open and was left untouched. After the first PCM stream it will never be NULL and we have code which checks for substream NULLity as indication if the stream is active or not. For the compressed cstream pointer the same has been done, this change will correct the handling of PCM streams.

ASoC: codecs: ab8500: Fix casting of private data

2026-06-01T15:39:28+00:00

[ Upstream commit a201aef1a88b675e9eb8487e27d14e2eef3cef80 ] ab8500_filter_controls[i].private_value is initialized using .private_value = (unsigned long)&(struct filter_control) {.count = xcount, .min = xmin, .max = xmax} thus it's a pointer to a struct filter_control casted to unsigned long. So to get back that pointer .private_data must be cast back, not its address. Fixes: 679d7abdc754 ("ASoC: codecs: Add AB8500 codec-driver") Signed-off-by: Christian A.

ASoC: SOF: compress: return the configured codec from get_params

2026-06-01T15:39:13+00:00

[ Upstream commit 2c4fdd055f92a2fc8602dcd88bcea08c374b7e8b ] The SOF compressed offload path accepts codec parameters in sof_compr_set_params() and forwards them to firmware as extended data in the SOF IPC stream params message. However, sof_compr_get_params() still returns success without filling the snd_codec structure. Since the compress core allocates that structure zeroed and copies it back to userspace on success, SNDRV_COMPRESS_GET_PARAMS returns an all-zero codec description even after the stream has been configured successfully. The stale TODO in this callback conflates get_params() with capability discovery. Supported codec enumeration belongs in get_caps() and get_codec_caps(). get_params() should report the current codec settings. Cache the codec accepted by sof_compr_set_params() in the per-stream SOF compress state and return it from sof_compr_get_params().
