Summary
In the Linux kernel, the following vulnerability has been resolved: coresight: syscfg: Fix memleak on registration failure in cscfg_create_device device_register() calls device_initialize(), according to doc of device_initialize: Use put_device() to give up your reference instead of freeing * @dev directly once you have called this function. To prevent potential memleak, use put_device() for error handling.
