[PATCH AUTOSEL 6.12 11/36] ALSA: ump: Indicate the inactive group in legacy substream names

From: Sasha Levin
Date: Wed Dec 11 2024 - 13:52:45 EST


From: Takashi Iwai <tiwai@xxxxxxx>

[ Upstream commit e29e504e7890b9ee438ca6370d0180d607c473f9 ]

Since the legacy rawmidi has no proper way to know the inactive group,
indicate it in the rawmidi substream names with "[Inactive]" suffix
when the corresponding UMP group is inactive.
