+Subject: ALSA: usb-audio - Avoid Oops after disconnect
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 78b8d5d2ee280c463908fd75f3bdf246bcb6ac8d upstream.
+
+As the release of substreams may be done asynchronously from the
+disconnection, close callback needs to check the shutdown flag before
+actually accessing the usb interface.
