ASoC: soc-pcm.c: use temporary variable at soc_get_playback_capture()
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.
