The devm_device_init_wakeup patch in linux-next/master commit b317268368546d6401af788648668f82e3ba1bd3 Author: Joe Hattori <joe@xxxxxxxxxxxxxxxxxxxxx> Date: Wed Dec 18 13:09:35 2024 +0900 PM: wakeup: implement devm_device_init_wakeup() helper Some drivers that enable device wakeup fail to properly disable it during their cleanup, which results in a memory leak. To address this, introduce devm_device_init_wakeup(), a managed variant of device_init_wakeup(dev, true). With this managed helper, wakeup functionality will be automatically disabled when the device is released, ensuring a more reliable cleanup process. This need for this addition arose during a previous discussion [1].
