It also fixes some issues, like a probe failure when failing to register WMI devices and a potential issue when opening the wmi char device. The changes where tested on a Dell Inspiron 3505, a Lenovo E51-80, a Acer Aspire E1-731 and a Asus PRIME B650-Plus motherboard and appear to work, but additional feedback especially on the third patch is appreciated.
