[PATCH v4 1/9] ata,scsi: Remove wrappers ata_sas_tport_{add,delete}()

[Niklas Cassel <cassel@xxxxxxxxxx>]

The ata_sas_tport_add() and ata_sas_tport_delete() wrappers only exist in
order to export the internal libata functions which they wrap.
Remove the wrappers and instead export the libata functions directly.
