## Overview

In the Linux kernel, the following vulnerability has been resolved:

platform/x86: asus-wireless: Fail probe when there is no ACPI match

Every platform driver can be forced to match a device that does not match
its list of device IDs because of device_match_driver_override(), so
platform drivers that rely on the existence of a device ACPI companion
object need to verify its presence.

asus_wireless_probe() returns success when acpi_match_acpi_device()
finds no match, leaving behind an input device that never reports
anything because the notify handler is not installed.  Worse, when the
driver is force-bound to a device without an ACPI companion, probe
still succeeds and stores a NULL companion pointer, which
asus_wireless_remove() later passes to acpi_dev_remove_notify_handler(),
leading to a NULL pointer dereference on unbind.

Return -ENODEV when the device does not match the ID table.  This also
covers the missing-companion case, because acpi_match_acpi_device()
rejects a NULL device.  Perform the check before allocating any driver
state, instead of after the input device has already been registered.
