Hello Daniel Baluta,

This is a semi-automatic email about new static checker warnings.

The patch 6324cf901e14: "ASoC: SOF: compr: Add compress ops implementation" from Jan 20, 2022, leads to the following Smatch complaint:

sound/soc/sof/compress.c:54 snd_sof_compr_fragment_elapsed() warn: variable dereferenced before check 'cstream' (see line 48)

sound/soc/sof/compress.c 47 { 48 struct snd_soc_pcm_runtime *rtd = cstream->private_data; 49 struct snd_compr_runtime *crtd = cstream->runtime; ^^^^^^^^^^^^^^^^ The patch adds a new dereference

50 struct snd_soc_component *component; 51 struct snd_compr_tstamp *tstamp; 52 struct snd_sof_pcm *spcm; 53 54 if (!cstream) ^^^^^^^^ The old code assumed "cstream" could be NULL

55 return; 56

regards, dan carpenter
