commit3eb27d3e32upstream. The MIDI2 gadget driver handled the default MIDI protocol version incorrectly due to the confusion of the protocol version passed via configfs (either 1 or 2) and UMP protocol bits (0x100 / 0x200). As a consequence, the default protocol always resulted in MIDI1. This patch addresses the misunderstanding of the protocol handling.
