Subject: bridge: fix netconsole setup over bridge
From: Cong Wang <cwang@xxxxxxxxxxxxxxxx>
[ Upstream commit dbe173079ab58a444e12dbebe96f5aec1e0bed1a ]
Commit 93d8bf9fb8f3 ("bridge: cleanup netpoll code") introduced
a check in br_netpoll_enable(), but this check is incorrect for
br_netpoll_setup(). This patch moves the code after the check
into __br_netpoll_enable() and calls it in br_netpoll_setup().
For br_add_if(), the check is still needed.
Fixes: 93d8bf9fb8f3 ("bridge: cleanup netpoll code")
