[PATCH 2.4.23-pre8] ieee1394 nodemgr deadlock

[Stelian Pop]

Hi,

This patch was submitted here a while ago, has been ack'ed by 
Ben Collins but it still hasn't made it into the 2.4 tree.

Marcelo, please apply it, without this patch kudzu deadlocks
on every boot on my RedHat laptop.

Thanks,

Stelian.
