When the\nendpoint is later torn down, snd_ump_endpoint_free() frees ump->out_cvts\na second time, resulting in a double free.\n\nThe host snd-usb-audio driver attaches the legacy rawmidi for any USB\nMIDI 2.0 (UMP) device, so a device that makes snd_rawmidi_new() fail\nreaches this path on enumeration.\n\nClear ump->out_cvts after freeing it on the error path so it is not\nfreed again during teardown.\n\nDiscovered by XBOW, triaged by Baul Lee <baul.lee@xbow.com>"
