Hi Paul,
Thanks for the review!
The lockdep warning did not noticeably affect the FC-49 functionality —
MIDI events were received fine via `aseqdump -p 128` both before and
after the patch. The warning is about a potential deadlock that lockdep
detected through lock ordering analysis, not one that was actually hit
during my testing. That said, under the right timing conditions the
deadlock is real and could hang the workqueue.
