------------------------------------------------------
Subject: sound: fix PCM substream list
From: Akinobu Mita <akinobu.mita@xxxxxxxxx>
If snd_pcm_new_stream() fails to initalize a substream (if
snd_pcm_substream_proc_init() returns error), snd_pcm_new_stream()
immediately return without unlinking that kfree()d substram.
It causes oops when snd_pcm_free() iterates the list of substream to
free them by invalid reference.
