Subject: net: kill netif_copy_real_num_queues()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=09626e9d153326ca82568e4e27f2daa53713992e;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

net: kill netif_copy_real_num_queues()

vlan was the only user of netif_copy_real_num_queues(),
but it no longer calls it after
commit 4af429d29b341bb1735f04c2fb960178 ("vlan: lockless transmit path").
So we can just remove it.
