Subject: vxlan: use a more suitable function when assigning NULL
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=57d88182ea3e8763111882671fd7462289272f64;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

vxlan: use a more suitable function when assigning NULL

When stopping the vxlan interface we detach it from the socket.
Use RCU_INIT_POINTER() and not rcu_assign_pointer() to do so.
