Subject: [PATCH] thermal/core: associate device tree node to thermal_cooling_device::device
Date: Mon,  6 Feb 2023 22:26:17 +0800	[thread overview]
Message-ID: <1675693577-2575-1-git-send-email-jianengchencool@gmail.com> (raw)

When adding a gpio property to a cooling device node in device tree, then in
thermal driver called gpiod_get(struct device *) to request this gpio will
fail, indicate cannot find gpio in device tree, because the of node do not
associate to struct device.
