[Stephen Rothwell]

Hi Linus,

After merging the gpio tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

drivers/gpio/gpiolib-acpi.c: In function 'acpi_gpio_adr_space_handler':
drivers/gpio/gpiolib-acpi.c:911:8: warning: unused variable 'err' 
[-Wunused-variable]
    int err;
        ^~~

Introduced by commit

  21abf103818a ("gpio: Pass a flag to gpiochip_request_own_desc()")
