[ Upstream commit 626c45d223e22090511acbfb481e0ece1de1356d ]
bcm2835-rpi.dtsi defines the behavior of the ACT LED, which is available on all Raspberry Pi boards. But there is no driver for this particual GPIO on CM3 in mainline yet, so this node was left incomplete without the actual GPIO definition. Since commit 025bf37725f1 ("gpio: Fix return value mismatch of function gpiod_get_from_of_node()") this causing probe issues of the leds-gpio driver for users of the CM3 dtsi file.
leds-gpio: probe of leds failed with error -2
Until we have the necessary GPIO driver hide the ACT node for CM3 to avoid this.
