6 | [ Upstream commit 07d86ca93db7e5cdf4743564d98292042ec21af7 ] | ||
7 | |||
8 | The 'umidi' object will be free'd on the error path by snd_usbmidi_free() | ||
9 | when tearing down the rawmidi interface. So we shouldn't try to free it | ||
10 | in snd_usbmidi_create() after having registered the rawmidi interface. | ||
