  firewire: obsolete usage of *-objs in Makefile for KUnit test (2024-05-09 08:06:22 +0900)

----------------------------------------------------------------
firewire updates for v6.10

During the development period of v6.8 kernel, it became evident that there
was a lack of helper utilities to trace the initial state of bus, while
investigating certain PHYs compliant with different versions of IEEE 1394
specification.

This series of changes includes the addition of tracepoints events,
provided by 'firewire' subsystem. These events enable tracing of how
firewire core functions during bus reset and asynchronous communication
over IEEE 1394 bus.

When implementing the tracepoints events, it was found that the existing
serialization and deserialization helpers for several types of
asynchronous packets are scattered across both firewire-core and
firewire-ohci kernel modules. A set of inline functions is newly added
to address it, along with some KUnit tests, serving as the foundation for
the tracepoints events. This renders the dispersed code obsolete.

The remaining changes constitute the final steps in phasing out the usage
of deprecated PCI MSI APIs, in continuation from the previous version.
