Reverting this commit seems to fix the problem.
93d8bf9fb8f3 ("bridge: cleanup netpoll code")

In the following code path, p->br->dev->npinfo is NULL at
br_netpoll_enable() because __netpoll_setup() assigns ndev->npinfo after
calling ndo_netpoll_setup().

  __netpoll_setup() -> br_netpoll_setup() -> br_netpoll_enable()

Thanks,
Toshiaki Makita
