## Description

In the Linux kernel, the following vulnerability has been resolved:  platform/x86: asus-wmi: fix resource leaks on probe failure  During driver initialization in asus_wmi_add(), various subsystems are registered sequentially. However, the error path labels are out of order relative to the registration sequence.  Specifically: 1. If asus_wmi_custom_fan_curve_init() fails, the driver jumps to    fail_custom_fan_curve. Because this label is placed below fail_sysfs,    it bypasses the cleanup calls for the input device and sysfs groups,    which were successfully registered before, leaking those resources. 2. If asus_screenpad_init() fails, the driver jumps to fail_screenpad.    Because fail_screenpad is placed below fail_backlight, it bypasses the    cleanup calls for backlight and rfkill, leaking those resources.  Fix these resource leaks by reordering the error path labels in asus_wmi_add() to match the exact reverse order of the resource allocations.
