[alsa-devel] fix memory leak in snd_pcm_set_chmap

[GitHub pull_request - opened]

alsa-project/alsa-lib pull request #10 was opened from conradjones:

asan detects this as a memory leak. 

snd_pcm_get_chmap clearly states that the caller is required to free the returned value, i cannot see it stored anywhere so cannot see how it could be freed.
