0b18ac42aa [SCSI] lpfc 8.1.6 : Fix Data Corruption in Bus Reset Path
This patch updates the lpfc driver to revision 8.1.6, which includes
the following changes:

 - Fix data corruption in SCSI BUS reset path, due to reusing
   the same request structure for each target.
 - Change version number to 8.1.6

defbcf11ab [SCSI] lpfc 8.1.5 : Fix cleanup code in the lpfc_pci_probe_one() error code path
Fix cleanup code in the lpfc_pci_probe_one() error code path.

This changes the original patch by:
  - hardsetting the return value from lpfc_pci_probe_one() to
    -ENODEV (negative value) if we fail attach
  - removes the checks from lpfc_pci_remove_one() validating the
    host and phba pointers as it's no longer needed.

9290831f00 [SCSI] lpfc 8.1.4 : Introduce lpfc_reset_barrier() function for resets on dual channel adapters
Introduce lpfc_reset_barrier() function for resets on dual channel adapters

Workaround for a hardware errata on dual channel asics. There is a
potential for the chip to lock up on a reset if a shared dma engine is in
use. The (ugly) work around requires a reset process which uses a mailbox
command to synchronize the independent channels prior to the reset to
avoid the issue. Unfortunately, the timing windows required to ensure this
workaround succeeds are very specific, meaning we can't release the cpu
during the barrier.

Fix deadlock in lpfc_fdmi_tmo_handler

lpfc_fdmi_tmo_handler was calling lpfc_fdmi_cmd with the host_lock
held.  lpfc_fdmi_cmd assumes the host_lock is released as it calls functions
that acquire the host_lock.  lpfc_fdmi_tmo_handler acquired the host_lock to
protect access to work_hba_events.  This was already checked in the worker
thread so we can remove that code completely and remove access to the
host_lock.
