Re: [PATCH 02/10] firewire-net: Rename a jump label in fwnet_broadcast_start()

The current CodingStyle says:  "Choose label names which say what the goto
does or why the goto exists."  Given the choice between /what/ and /why/,
I for one lean towards /why/.

In this instance, the what and why is "clean up and exit after an error
occurred".  'failed' looks to me to be a better shorthand of this than
'stop_broadcast'.  The latter merely says /how/ the cleanup is done.

I see no reason to remove the blank line between the return statement and
the label.
