Subject: [PATCH v3 0/3]  hisi_sas: DIF support


This patchset introduces support to the driver for DIF (or PI -protection
information).

We are dropping DIX support for now, based on issues discussed in the
following:
https://marc.info/?l=linux-scsi&m=154357719329297&w=4

We will only support PI in v3 hw at the moment, even though previous hw
versions also support it.

The series is broken down as follows:
- Fix pre-existing sparse warnings
- Tidy sg table size config
- Some tidy-up to accept PI support
- Add components for PI support for main and v3 driver

Difference v1->v2:
- drop scsi_prot_op_normal()

v2->v3:
- fix sparse warnings
- drop DIX support

John Garry (1):
  scsi: hisi_sas: Fix warnings detected by sparse

Xiang Chen (3):
  scsi: hisi_sas: Relocate some code to reduce complexity
  scsi: hisi_sas: Make sg_tablesize consistent value
  scsi: hisi_sas: Add support for DIF feature for v3 hw
