+Subject: ALSA: usb-audio: avoid freeing umidi object twice
+
+commit 07d86ca93db7e5cdf4743564d98292042ec21af7 upstream.
+
+The 'umidi' object will be free'd on the error path by snd_usbmidi_free()
+when tearing down the rawmidi interface. So we shouldn't try to free it
+in snd_usbmidi_create() after having registered the rawmidi interface.
+
+Found by KASAN.
+
+CVE: CVE-2016-2384
+Upstream-Status: Backport
