bridge: mcast: Use spin_lock() instead of spin_lock_bh()
IGMPv3 / MLDv2 Membership Reports are only processed from the data path with softIRQ disabled, so there is no need to call spin_lock_bh(). Use spin_lock() instead. This is consistent with how other IGMP / MLD packets are processed. Signed-off-by: Ido Schimmel <idosch@nvidia.com> Acked-by: Nikolay Aleksandrov <razor@blackwall.org> Signed-off-by: David S.
