linux-next: build warning after merge of the gpio-brgl tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi Bartosz,

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

drivers/gpio/gpio-davinci.c: In function 'davinci_gpio_get_irq_chip':
drivers/gpio/gpio-davinci.c:472:9: warning: function returns address of local variable [-Wreturn-local-addr]
  return &gpio_unbanked.chip;
         ^~~~~~~~~~~~~~~~~~~
drivers/gpio/gpio-davinci.c: In function 'keystone_gpio_get_irq_chip':
drivers/gpio/gpio-davinci.c:480:9: warning: function returns address of local variable [-Wreturn-local-addr]
  return &gpio_unbanked;
         ^~~~~~~~~~~~~~

Introduced by commit
