If anyone has any objections, please let me know. ------------------ From: Bartosz Golaszewski commit 4aacf509e537a711fa71bca9f234e5eb6968850e upstream. Platform devices created with platform_device_alloc() call platform_device_release() when the last reference to the device's kobject is dropped. This function calls of_node_put() unconditionally. This works fine for devices created with platform_device_register_full() but users of the split approach (platform_device_alloc() + platform_device_add()) must bump the reference of the of_node they assign manually. Add the missing call to of_node_get().
