Hi,

IEEE 1394 bus is under bus-reset state when the physical state of bus is
changed; e.g. bus topology change by adding new nodes in the bus. It is
important to handle the state appropriately for the maintenance of bus.

This series of change adds some tracepoints events to trace the events
related to bus-reset. Some kernel log messages are obsoleted and
deleted. It also includes for 1394 OHCI driver so that bus-reset IRQ
event is recorded as much as possible, and obsoletes bus-resets bit
from debug parameter successfully.

Takashi Sakamoto (5):
firewire: ohci: add bus-reset event for initial set of handled irq
firewire: ohci: obsolete OHCI_PARAM_DEBUG_BUSRESETS from debug module
parameter
firewire: core: add tracepoints events for initiating bus reset
Revert "firewire: core: option to log bus reset initiation"
firewire: core: add tracepoint event for handling bus reset
