From 78bd2b4f6e7c0522cc8bc8ad651f20813ae06f6c Mon Sep 17 00:00:00 2001 From: Xiaofei Tan Date: Mon, 21 May 2018 18:09:21 +0800 Subject: scsi: hisi_sas: Include TMF elements in struct hisi_sas_slot In future scenarios we will want to use the TMF struct for more task types than SSP. As such, we can add struct hisi_sas_tmf_task directly into struct hisi_sas_slot, and this will mean we can remove the TMF parameters from the task prep functions.
