The mistake which is fixed here is present since firewire-ohci was added 
in 2.6.22.  However, for a smooth submission to stable, the patched file...

>> --- linux-2.6.31-rc9.orig/drivers/firewire/ohci.c
>> +++ linux-2.6.31-rc9/drivers/firewire/ohci.c

...has to be drivers/firewire/fw-ohci.c in kernels before 2.6.31-rc1.

As hinted at in the changelog, I personally don't consider the fix 
urgent because there are a few more self ID consistency checks in place 
which catch a variety of real and theoretical corruptions, but I don't 
claim that I'm appropriately aware of all possibilities.
