Subject: problem with function vlan_get_protocol()

Hi,all

in file   inclue/linux/if_vlan.h

there is a statement in function vlan_get_protocol()

	if (likely(protop))
		protocol = *protop;

do we need an else branch on pointer protop failed through the else is unlikely 

	if (likely(protop))
		protocol = *protop;
    else
		protocol = proto;

thanks
