Hi Stefan,

> According to the devicetree binding the shutdown and device wake
> GPIOs are optional. Since commit 3e81a4ca51a1 ("Bluetooth: hci_bcm:
> Mandate presence of shutdown and device wake GPIO") this driver
> won't probe anymore on Raspberry Pi 3 and Zero W (no device wake GPIO
> connected). So fix this regression by reverting this commit partially.
