Looking at kernel changelog I see:

   $  git-show 4e9b82693542003b028c8494e9e3c49615b91ce7 | head
   commit 4e9b82693542003b028c8494e9e3c49615b91ce7
   Author: Thomas Graf <tgraf at suug.ch>
   Date:   Mon Nov 27 09:25:58 2006 -0800

       [NETLINK]: Remove unused dst_pid field in netlink_skb_parms
       
       The destination PID is passed directly to netlink_unicast()
       respectively netlink_multicast().

And continuing to read it seems enought this patch:

   diff --git a/drivers/pps/pps.c b/drivers/pps/pps.c

Please, test the code and report possible bugs! Expecially should be
tested systems with multiple GPS antennas.

Ciao,

Rodolfo
