genetlink: Optimize genl_register_family()
genl_register_family() doesn't need to call genl_family_find_byid when GENL_ID_GENERATE is passed during register. Patch on net-next-2.6, compile and reboot testing only. Signed-off-by: Krishna Kumar <krkumar2@in.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
