[ACPI] acpi_register_gsi() fix needed for ACPICA 20051021
Use the #define for ACPI_LEVEL_SENSITIVE instead of assuming non-zero, because ACPICA 20051021 changes its value to zero. Also, use uniform variable names: edge_level -> triggering active_high_low -> polarity Signed-off-by: Len Brown <len.brown@intel.com>
