Subject: [PATCH for 4.9 33/59] serial: 8250: moxa: Store num_ports in brd

From: "Matwey V. Kornilov" <matwey@....msu.ru>

[ Upstream commit 9c4b60fe5313c125b1bf68ef04b0010512c27f2d ]

When struct moxa8250_board is allocated, then num_ports should
be initialized in order to use it later in moxa8250_remove.
