Re: [PATCH 27/36] ALSA: seq: Add port direction to snd_seq_port_info

Add a new field "direction" to snd_seq_port_info for allowing a client to tell the expected direction of the port access. A port might still allow subscriptions for read/write (e.g. for MIDI-CI) even if the primary usage of the port is a single direction (either input or output only). This new "direction" field can help to indicate such cases.

When the direction is unspecified at creating a port and the port has either read or write capability, the corresponding direction bits are set automatically as default.
