iser-target: introduce fast memory registration mode (FRWR)

Hello Vu Pham,

This is a semi-automatic email about new static checker warnings.

The patch 12050ce23475: "iser-target: introduce fast memory registration mode (FRWR)" from Aug 28, 2013, leads to the following Smatch complaint:

drivers/infiniband/ulp/isert/ib_isert.c:622 isert_connect_release()
warn: variable dereferenced before check 'device' (see line 598)

drivers/infiniband/ulp/isert/ib_isert.c
597 if (device->use_frwr)

                    ^^^^^^^^^^^^^^^^

Patch introduces dereference.

   598			isert_conn_free_frwr_pool(isert_conn);
   599	

[ snip ]

620 kfree(isert_conn);
621
622 if (device)

                    ^^^^^^

Existing check.

   623			isert_device_try_release(device);
   624

dan carpenter
