ipv6: addrconf: Use normal debugging style
Remove local ADBG macro and use netdev_dbg/pr_debug Miscellanea: o Remove unnecessary debug message after allocation failure as there already is a dump_stack() on the failure paths o Leave the allocation failure message on snmp6_alloc_dev as there is one code path that does not do a dump_stack() Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>
