From d2d5a6b0253d30ef04d513447cdd00df4fa627c3 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Mon, 22 Jul 2019 12:37:10 +0900 Subject: ALSA: firewire-motu: more code refactoring for MOTU data block processing layer MOTU data block processing layer has some tracepoints events. This commit is code refactoring to split probing the events from processing data blocks.
