The rule is follow the coding style in the file, unless there's
something really wrong with it (which there might be in the case of
really old drivers).  The reason is that a mixture of coding styles
makes the file much harder to read than a single consistent style.

In this case, if you look at libata-acpi.c you see all continuation
lines of function calls are aligned with open braces.
