From ff7b190aef6cccdb6f14d20c5753081fe6420e0b Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sun, 11 May 2025 15:45:27 +0200 Subject: [PATCH 1/7] ALSA: seq: Fix delivery of UMP events to group ports When an event with UMP message is sent to a UMP client, the EP port receives always no matter where the event is sent to, as it's a catch-all port. OTOH, if an event is sent to EP port, and if the event has a certain UMP Group, it should have been delivered to the associated UMP Group port, too, but this was ignored, so far. This patch addresses the behavior. Now a UMP event sent to the Endpoint port will be delivered to the subscribers of the UMP group port the event is associated with. The patch also does a bit of refactoring to simplify the code about __deliver_to_subscribers().
