acpi_evaluate_integer() takes a pathname parameter which contains the
name of the entity to evaluate underneath the given handle, so calling
acpi_get_handle() beforehand is redundant.  Replace the call to
acpi_get_handle() with a call to acpi_evaluate_integer(), thus
eliminating the need for a local variable storing the handle.  Adjust
whitespace to make checkpatch happy.
