Hotplug testing with libsas currently encounters a 55 second wait for
link recovery to give up. In the case where the user trusts the
response time of their devices permit the recovery attempts to be
limited to one.

Dan Carpenter (2):
isci: make function declaration match implementation
isci: add a couple __iomem annotations
Dan Williams (1):
isci: fix isci_pci_probe() generates warning on efi failure path
is unlikely and we keep the
memory around in the success case just defer all de-allocation to devm.

I wonder if we are preventing scsi_device_dev_release_usercontext() from
making forward progress?

We hope they will get to the upstream kernel soon...
They were tagged for -next and managed to miss the merge window because
it closed early.
Just a one-off growing pain of the new process:

but recent sysfs changes now exposes this problem. Libsas should delete
all the devices from rphy down before deleting the parent port.
