[PATCH v5 06/23] scsi: hisi_sas: relocate get_ncq_tag_v2_hw()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Xiang Chen <chenxiang66@xxxxxxxxxxxxx>

Relocate get_ncq_tag_v2_hw() to a common location, as
future hw versions will require it.
Also rename with "hisi_sas_" prefix for consistency.
