Subject: [PATCH 5.1 03/62] hv_netvsc: Fix extra rcu_read_unlock in netvsc_recv_callback()
From: Haiyang Zhang <haiyangz@...rosoft.com>
[ Upstream commit be4363bdf0ce9530f15aa0a03d1060304d116b15 ]
There is an extra rcu_read_unlock left in netvsc_recv_callback(),
after a previous patch that removes RCU from this function.
This patch removes the extra RCU unlock.
Fixes: 345ac08990b8 ("hv_netvsc: pass netvsc_device to receive callback")
