Vulnerability Summary

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.
