Subject: [PATCH] ALSA: usb-audio: avoid freeing umidi object twice
|
|
|
|
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.
|
|
