From: Emmanuel Grumbach <emmanuel.grumb...@intel.com>
commit ba3224db78034435e9ff0247277cce7c7bb1756c upstream.
The index for the elements of the ACPI object we dereference
was static. This means that if we called the function twice
we wouldn't start from 3 again, but rather from the latest
index we reached in the previous call.
This was dutifully reported by KASAN.
Fix this.
