Subject: [PATCH] netfilter: bridge: refcount fix

Hi David

I found following by code review only, I am not sure it is critical enough for net-2.6

This is a stable candidate, bug is more than 2 years old.

Thanks

commit f216f082b2b37c4943f1e7c393e2786648d48f6f
([NETFILTER]: bridge netfilter: deal with martians correctly)
added a refcount leak on in_dev.
