+Subject: Revert "usb: gadget: inode.c: fix unbalanced spin_lock in ep0_write"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This reverts commit abb540b5397674243994c5327146b6fed7339b71 which is
+commit b7bd98b7db9f upstream.  I had added it to make another patch
+apply cleanly, but as Ben points out, that was wrong.
