Hi Linus,

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

drivers/bluetooth/hci_bcm.c: In function 'bcm_acpi_probe':
drivers/bluetooth/hci_bcm.c:429:9: error: too few arguments to function 'devm_gpiod_get'
  gpio = devm_gpiod_get(&pdev->dev, "device-wakeup");
         ^
In file included from drivers/bluetooth/hci_bcm.c:32:0:
include/linux/gpio/consumer.h:73:32: note: declared here
 struct gpio_desc *__must_check devm_gpiod_get(struct device *dev,
                                ^
drivers/bluetooth/hci_bcm.c:437:9: error: too few arguments to function 'devm_gpiod_get'
  gpio = devm_gpiod_get(&pdev->dev, "shutdown");

Caused by commit

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

Interacting with commit

  0395ffc1ee05 ("Bluetooth: hci_bcm: Add PM for BCM devices")

from the bluetooth tree.

I added the following merge fix patch:
