From: Alexey Starikovskiy <astarikovskiy@xxxxxxx> breakage introduced by following patch commit 27663c5855b10af9ec67bc7dfba001426ba21222 Author: Matthew Wilcox <willy@xxxxxxxxxxxxxxx> Date: Fri Oct 10 02:22:59 2008 -0400 acpi_evaluate_integer() does not clear passed variable if there is an error at evaluation. So if we ignore error, we must supply initialized variable.
