acpica-tools/dbtest.patch

On s390, GCC does not like the string initialization in this case.  When
ValueToWrite is initialized this way, GCC tries to copy the entire string
into an ACPI_OBJECT instead of just the pointer (see the use in the call
to memcpy()).  So, move the init so GCC recognizes that ValueToWrite is
only a pointer, and not a whole string that needs to be moved.
