The variable ret is being initialized with a value that is never read, the
assignment is redundant and can be removed.

lockdep_assert_held() is better suited to checking locking requirements, since
it won't get confused when someone else holds the lock. This is also a step
towards possibly removing spin_is_locked().

While HBA reset is in progress, if IO/TM completion is received for the
same IO then IO/TM completion path releases the driver private resources
associated with IO. This fix prevents releasing the resources in
IO and TM completion path if HBA reset is in progress.

Cisco has developed a new PCI HBA interface called sNIC, which stands for
SCSI NIC. This is a new storage feature supported on specialized network
adapter. The new PCI function provides a uniform host interface and abstracts
backend storage.
