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: and

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

- re-add DIX support as RFC - do not commit please!
- also DIX support is labelled experimental in the driver

- fix sparse warnings
- drop DIX support

- 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
