Summary
USB: gadget: f_midi: f_midi_complete to call queue_work
Details

In the Linux kernel, the following vulnerability has been resolved:

USB: gadget: fmidi: fmidicomplete to call queuework

When using USB MIDI, a lock is attempted to be acquired twice through a re-entrant call to fmiditransmit, causing a deadlock.

Fix it by using queuework() to schedule the inner fmidi_transmit() via a high priority work queue from the completion handler.
