Simple patch to correctly "put" ipv6 device none

Description Chris Lalancette 2007-03-05 23:09:31 UTC 
Description of problem:
Running "cat /proc/net/anycast6" in the current RHEL-5 current causes a
reference leak, where we do an "in6_dev_get", but never a "in6_dev_put" in
ac6_get_first().  This results in ethernet devices that cannot be removed with
rmmod, and requires a reboot to fix.  The solution is from an upstream patch here:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=aa6e4a96e7589948fe770744f7bb4f0f743dddaa

which just adds the in6_dev_put.
