soc_get_playback_capture() (A) returns number of substreams for playback/capture (B). (A) static int soc_get_playback_capture(..., (B) int *playback, int *capture) { ... for_each_xxx(...) { if (xxx) return -EINVAL; => *playback = 1; ... => *capture = 1; ... } ... } But, it is directly updating playback/capture which is the result of this function even though it might be error. It should be updated in case of succeed only. This patch updates it.
