local_bh_disable() + spin_lock() is equivalent to spin_lock_bh(), same for the unlock/enable case, so replace the calls by the appropriate wrappers. Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> --- net-next 3c8e43ba "sctp: remove macros sctp_spin_[un]lock" and net-next 79b91130 "sctp: remove macros sctp_local_bh_{disable|enable}" reverted scpt macros back to spin_lock/unlock and local_bh_disable/enable which can be consolidated to spin_lock_bh/spin_unlock_bh in this case.
