From 07d86ca93db7e5cdf4743564d98292042ec21af7 Mon Sep 17 00:00:00 2001 From: Andrey Konovalov Date: Sat, 13 Feb 2016 11:08:06 +0300 Subject: 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. Found by KASAN.
