Hi Sam,

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

drivers/gpio/sch_gpio.c: In function 'sch_gpio_probe':
drivers/gpio/sch_gpio.c:232: warning: ignoring return value of 'gpiochip_remove', declared with attribute warn_unused_result
drivers/gpio/sch_gpio.c: In function 'sch_gpio_remove':
drivers/gpio/sch_gpio.c:245: warning: ignoring return value of 'gpiochip_remove', declared with attribute warn_unused_result
drivers/gpio/sch_gpio.c:246: warning: ignoring return value of 'gpiochip_remove', declared with attribute warn_unused_result

Introduced by commit 4faabcde03a89836169f1437127226f4b0714070 ("gpio: add
Intel SCH GPIO controller driver").
