From 001c1ff5dc397bc26a3d1a0da8733c179f39c946 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Tue, 25 Jun 2024 12:18:05 +0900 Subject: firewire: ohci: add support for Linux kernel tracepoints The Linux Kernel Tracepoints framework is enough useful to trace the interaction between 1394 OHCI hardware and its driver. This commit adds firewire_ohci subsystem to use the framework. It is defined as the different subsystem from the existing firewire subsystem. The definition file for the existing subsystem is slightly changed so that both subsystems are available in 1394 OHCI driver.
