Change it to the style like other macros:

Single statement macros do _not_ need to use
"do { foo(); } while (0)"
and should be written as
"foo()"
OK, will remove the do {} while (0).
But I think we'd better keep the macro, or rename it to something
more meaningful. At least we can use it to avoid adding "ACPI OVERRIDE:"
prefix every time. Maybe this is why it is defined.
Thanks. :)
