This might cause memory corruption should\nwmi_char_open() be unable to find its driver, something which can\nhappen when the associated WMI device is deleted in wmi_free_devices().\n\nFix the problem by using the miscdevice pointer to retrieve the WMI\ndevice data associated with a char device using container_of(). This\nalso avoids wmi_char_open() picking a wrong WMI device bound to a\ndriver with the same name as the original driver."
