Summary
platform/x86: mxm-wmi: fix memleak in mxm_wmi_call_mx[ds|mx]()
Details

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

platform/x86: mxm-wmi: fix memleak in mxmwmicall_mxds|mx

The ACPI buffer memory (out.pointer) returned by wmievaluatemethod() is not freed after the call, so it leads to memory leak.

The method results in ACPI buffer is not used, so just pass NULL to wmievaluatemethod() which fixes the memory leak.
