If anyone has any objections, please let me know. ------------------ From: Johan Hovold commit 7ecd9a3f062147400e605713724dd67dbb7e5053 upstream. The platform device must be registered as wakeup capable before registering the class device, or the wakealarm attribute will not be created. Also make sure to unregister the wakeup source on probe errors.
