commit e5c399b0bd6490c12c0af2a9eaa9d7cd805d52c9 upstream.
Commit ea6f3af4c5e63f69 ("ACPI: GED: add support for _Exx / _Lxx handler methods") added a reference to the 'triggering' field of either the normal or the extended ACPI IRQ resource struct, but inadvertently used the wrong pointer in the latter case. Note that both pointers refer to the same union, and the 'triggering' field appears at the same offset in both struct types, so it currently happens to work by accident. But let's fix it nonetheless
