From: Andrey Konovalov <[email protected]> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== 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.
