Hi Linus,

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

drivers/input/touchscreen/elants_i2c.c: In function 'elants_i2c_probe':
drivers/input/touchscreen/elants_i2c.c:1176:19: error: too few arguments to function 'devm_gpiod_get'
ts->reset_gpio = devm_gpiod_get(&client->dev, "reset");
In file included from drivers/input/touchscreen/elants_i2c.c:41:0:
include/linux/gpio/consumer.h:73:32: note: declared here
struct gpio_desc *__must_check devm_gpiod_get(struct device *dev,

Caused by commit

b17d1bf16cc7 ("gpio: make flags mandatory for gpiod_get functions")

Interacting with commit

afe10358e47a ("Input: elants_i2c - wire up regulator support")

from the input tree.

I have added the following merge fix patch:
