The coding style where calling this interface is inconsistent with other
interfaces for sata devices. The standard style for other sata interfaces
is like:

    #ifdefine CONFIG_SCSI_SAS_ATA
    void sas_ata_task_abort(struct sas_task *task);
    #else
    static inline void sas_ata_task_abort(struct sas_task *task)
    {
    }
    #endif

And the callers does not have to do things like "#ifdefine CONFIG_SCSI_SAS_ATA"
and may call the interface directly. So follow the standard style here.

nit: capitalize acronyms, so /s/sata/SATA/

nit: is there a blank line missing?
