[v1] libsas: Some tidy-up

[PATCH 08/10] scsi: libsas: Delete sas_ata_task.set_affil_pol

Posted by John Garry 2 years, 4 months ago

Since libsas was introduced in commit 2908d778ab3e ("[SCSI] aic94xx: new
driver"), sas_ata_task.set_affil_pol is never set, so delete it and the
reference in asd_build_ata_ascb().
