Pull firewire fixes from Takashi Sakamoto:
"A workaround to suppress the continuous bus resets in the case that
older devices are connected to the modern 1394 OHCI hardware and
devices

In IEEE 1394 Amendment (IEEE 1394a-2000), the short bus reset is added
to resolve the shortcomings of the long bus reset in IEEE 1394-1995.
However, it is well-known that the solution is not necessarily
effective in the mixing environment that both IEEE 1394-1995 PHY and
IEEE 1394a-2000 (or later) PHY exist, as described in section 8.4.6.2
of IEEE 1394a-2000.

The current implementation of firewire stack schedules the short bus
reset when attempting to resolve the mismatch of gap count in the
certain generation of bus topology. It can cause the continuous bus
reset in the issued environment.

The workaround simply uses the long bus reset instead of the short bus
reset. It is desirable to detect whether the issued environment or
not. However, the way to access PHY registers from remote note is
firstly defined in IEEE 1394a-2000, thus it is not available in the
case"
