Subject: [PATCH 0/3] hisi_sas: some CQ processing fixes

This patchset fixes some issues related to servicing of the
completion queue interrupt.
The major fix is that sensitive hisi_hba structures need to be
locked when free'ing a slot.
Another modification is that the v2 hw completion queue irq is
now serviced with a tasklet, as too much work was being done in
the ISR.

John Garry (3):
  scsi: hisi_sas: service v2 hw CQ ISR with tasklet
  scsi: hisi_sas: lock sensitive regions when servicing CQ interrupt
  scsi: hisi_sas: lock sensitive region in hisi_sas_slot_abort()
