Rafael J. Wysocki e5b681822c ACPI: CPPC: Avoid out of bounds access when parsing _CPC data 
commit 40d8abf364 upstream.

If the NumEntries field in the _CPC return package is less than 2, do
not attempt to access the "Revision" element of that package, because
it may not be present then.

Fixes: 337aadff8e ("ACPI: Introduce CPU performance controls using CPPC")
