Subject: [PATCH v4 0/5]  hisi_sas: DIF support

This patchset introduces support to the driver for DIF/DIX.

We are making DIX support as RFC for now, based on issues discussed in the
following:
https://marc.info/?l=linux-scsi&m=154357719329297&w=4 and
https://marc.info/?l=linux-scsi&m=154406987703456&w=2

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

Differences:
v3->v4:
- re-add DIX support as RFC - do not commit please!
- also DIX support is labelled experimental in the driver

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

v1->v2:
- drop scsi_prot_op_normal()

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

Xiang Chen (4):
  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
  scsi: hisi_sas: Add support for DIX feature for v3 hw as experimental
