Hi All,

Please help me on this question.

Hi All,

In the following function

dpcm_fe_dai_open

Why the code is proceeding further if dpcm_path_get returns zero, if dpcm_path_get returns zero implies there is no vaild path setup.

technically we should return from the function when there is no valid path setup, still we proceed further de-referencing the pointer at the exit of this function through dpcm_path_put(&list);

please let me know why we are not returning when dpcm_path_get returns zero.

static int dpcm_fe_dai_open(struct snd_pcm_substream *fe_substream) { .... if (dpcm_path_get(fe, stream, &list) <= 0) { dev_dbg(fe->dev, "ASoC: %s no valid %s route\n", fe->dai_link->name, stream ? "capture" : "playback");

        /*we need to return if there is no vaild paths available*/

} .... dpcm_path_put(&list); }
