From b8e49e24cdba27a0810a0988e810e2c68f2033cb Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 28 Nov 2024 08:47:33 +0100 Subject: [PATCH] ALSA: seq: Notify client and port info changes It was supposed to be notified when a sequencer client info and a port info has changed (via SNDRV_SEQ_EVENT_CLIENT_CHANGE and SNDRV_SEQ_EVENT_PORT_CHANGE event, respectively), and there are already helper functions. But those aren't really sent from the driver so far, except for the recent support of UMP, simply due to the lack of implementations. This patch adds the missing notifications at updating the client and the port info. The formerly added notification for UMP is dropped because it's handled now in the port info side.
