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

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi Greg,

After merging the tty tree, today's linux-next build (x86_64
allmodconfig) produced these warnings:

drivers/tty/serial/serial_mctrl_gpio.c: In function 'mctrl_gpio_init':
drivers/tty/serial/serial_mctrl_gpio.c:110:4: warning: return makes pointer from integer without a cast
    return PTR_ERR(gpios->gpio[i]);
    ^
drivers/tty/serial/serial_mctrl_gpio.c:90:6: warning: unused variable 'err' [-Wunused-variable]
  int err;
      ^

Introduced by commit 1d267ea6539f ("serial: mctrl-gpio: simplify init
routine").
