+Subject: ALSA: pcm: fix out-of-bounds in snd_pcm_state_names
+
+From: Jason Zhang <jason.zhang@rock-chips.com>
+
+commit 2b3a7a302c9804e463f2ea5b54dc3a6ad106a344 upstream.
+
+The pcm state can be SNDRV_PCM_STATE_DISCONNECTED at disconnect
+callback, and there is not an entry of SNDRV_PCM_STATE_DISCONNECTED
+in snd_pcm_state_names.
+
+This patch adds the missing entry to resolve this issue.
