    Subject[PATCH 5.1 03/62] hv_netvsc: Fix extra rcu_read_unlock in netvsc_recv_callback()
    Date
    From: Haiyang Zhang <haiyangz@microsoft.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")
