[Sasha Levin <sashal@xxxxxxxxxx>]

From: YueHaibing <yuehaibing@xxxxxxxxxx>

[ Upstream commit 68e03b85474a51ec1921b4d13204782594ef7223 ]

when do randbuilding, I got this error:

In file included from drivers/hwmon/pmbus/ucd9000.c:19:0:
./include/linux/gpio/driver.h:576:1: error: redefinition of gpiochip_add_pin_range
 gpiochip_add_pin_range(struct gpio_chip *chip, const char *pinctl_name,
 ^~~~~~~~~~~~~~~~~~~~~~
In file included from drivers/hwmon/pmbus/ucd9000.c:18:0:
./include/linux/gpio.h:245:1: note: previous definition of gpiochip_add_pin_range was here
