There are five libsas consumers (callers of sas_register_ha): hisi_sas,
isci, pm8001, aic94xx, and mvsas. Only hisi_sas needs a driver-side
change, because it is the only driver that satisfies all three
conditions below simultaneously.

I am saying that other drivers use sas_resume_ha() and you are changing the behavior of that function - how can you guarantee that you are not causing regression for that those other drivers?
