Subject: [PATCH 0/8] firewire: store the numeric identifier of card in data structure for tracepoint events

Hi,

In v6.10 kernel, some tracepoints events are added to record
IEEE 1394 asynchronous communication. In the case that multiple 1394 OHCI
controllers are available in Linux system, it is hard to distinguish
the controller used for the communication, since these events have no
member in their data structure to express the used controller. It is a
bit inconvenient to diagnose things.

This series of patches is an attempt to solve the issue. In Linux
FireWire core, the available controllers are maintained in list, and
each of them has its own numeric identifier (=card_index). In this
series, the index value is added to the data structure.

I would like to put the change to v6.10-rc4 (or later) as the part of
fixes if receiving no objections.
