linux-next: build failure after merge of the gpio tree

Hi Linus,

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

drivers/media/i2c/tc358743.c: In function 'tc358743_probe_of':
drivers/media/i2c/tc358743.c:1786:22: error: too few arguments to function 'devm_gpiod_get'
state->reset_gpio = devm_gpiod_get(dev, "reset");
^
In file included from drivers/media/i2c/tc358743.c:34:0:
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

256148246852 ("[media] tc358743: support probe from device tree")

from the v4l-dvb tree.

I have added the following fix patch for today:
