Re: [PATCH 32/36] ALSA: seq: ump: Create UMP Endpoint port for broadcast

Create a sequencer port for broadcasting the all group inputs at the port number 0. This corresponds to a UMP Endpoint connection; application can read all UMP events from this port no matter which group the UMP packet belongs to.

Unlike seq ports for other UMP groups, a UMP Endpoint port has no SND_SEQ_PORT_TYPE_MIDI_GENERIC bit, so that it won't be treated as a normal MIDI 1.0 device from legacy applications.

The port is named as "MIDI 2.0" to align with representations on other operation systems.
