From 8d3f1fdf521165cac96a21e35f5a1630147d91b1 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Sun, 19 May 2019 19:01:09 +0900 Subject: [PATCH] ALSA: firewire-lib: unify tracing events to 'amdtp_packet' event Now four events of this module have the same arguments and probe timing. This commit adds a new event, 'amdtp_packet', and replace them. Filtering functionality of tracing framework is available to pick up events for inbound/outbound isochronous packets.
