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

[Stephen Rothwell]

Hi Linus,

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

drivers/gpio/gpiolib.c: In function 'gpiochip_irqchip_init_valid_mask':
drivers/gpio/gpiolib.c:1474:6: warning: unused variable 'i' [-Wunused-variable]
  int i;
      ^

Introduced by commit

  923a654c186c ("gpiolib: Re-use bitmap_fill() instead of open coded loop")
