target is not an optional, pls looks at aml_add and use
helper to make patch correct and smaller
Indeed, i will change it to:
/* ACPI 1.0b: 16.2.5.4 Type 2 Opcodes Encoding: DefConcat */
Aml *aml_concatenate(Aml *source1, Aml *source2, Aml *target)
{
return build_opcode_2arg_dst(0x73 /* ConcatOp */, arg1, arg2, dst);
}
And make a assert for @target to ensure it can not be NULL.
