Currently driver retrieve the sas_devie/sas_expander objects
from corresponding object's lists using just device's
SAS Address. Now driver will retrieve the objects from the
corresponding objects list using device's SAS Address
and PhysicalPort(or PortID) number.
where
PhysicalPort number - Port number of the HBA through which this
device is accessing.
Here are the list of objects that driver retrieves based on
SAS Address & PhysicalPort number,
* Retrieve sas_device object from sas_device_list using device's
SAS Address & PhysicalPort number,
* Retrieve sas_expander object from sas_expander_list using expander
device's SAS Address & PhysicalPort number,
Also, where ever driver is matching the objects with device's
SAS Address, now, in addition to it driver has to match the device
PhysicalPort number also.
Added additional function parameter named 'port' of type
struct hba_port in below list of functions,
* mpt3sas_expander_remove()
* mpt3sas_device_remove_by_sas_address()
* mpt3sas_scsih_expander_find_by_sas_address()
* mpt3sas_get_sdev_by_addr()
* __mpt3sas_get_sdev_by_addr()
* _scsih_ublock_io_device()
* _transport_sas_node_find_by_sas_address()
* _transport_sanity_check()
