From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx> Build bot reports the following build issue after commit 9091373ab7ea ("gpio: remove less important #ifdef around declarations): 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 gpiochip_add_pin_range(struct gpio_chip *chip, const char *pinctl_name, ^~~~~~~~~~~~~~~~~~~~~~ In file included from drivers/hwmon/pmbus/ucd9000.c:19:0: >> include/linux/gpio/driver.h:583:1: error: redefinition of 'gpiochip_add_pingroup_range' gpiochip_add_pingroup_range(struct gpio_chip *chip, ^~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from drivers/hwmon/pmbus/ucd9000.c:18:0: include/linux/gpio.h:254:1: note: previous definition of 'gpiochip_add_pingroup_range' was here gpiochip_add_pingroup_range(struct gpio_chip *chip, ^~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from drivers/hwmon/pmbus/ucd9000.c:19:0: >> include/linux/gpio/driver.h:591:1: error: redefinition of 'gpiochip_remove_pin_ranges' gpiochip_remove_pin_ranges(struct gpio_chip *chip) ^~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from drivers/hwmon/pmbus/ucd9000.c:18:0: include/linux/gpio.h:263:1: note: previous definition of 'gpiochip_remove_pin_ranges' was here gpiochip_remove_pin_ranges(struct gpio_chip *chip) This is caused by conflicting defines from linux/gpio.h and linux/gpio/driver.h. Drivers should not include both the legacy and the new API headers. This driver doesn't even use linux/gpio.h so remove it.
