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.
