linux-next: build warning after merge of the tty tree

[Stephen Rothwell]

Hi Greg,

After merging the tty tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

drivers/tty/serial/8250/8250_exar.c: In function 'pci_xr17v35x_setup':
drivers/tty/serial/8250/8250_exar.c:380:31: warning: unused variable 'board' 
[-Wunused-variable]
  const struct exar8250_board *board = priv->board;
                               ^~~~~

Introduced by commit

  328c11f24b57 ("serial: 8250_exar: Remove useless has_slave member")
