> In function add_port(), pointer p is not released in error paths.

1. I would prefer to describe that an ib_port data structure was not released
   in some error cases.
   How relevant can its size be here?


> Fix this issue by adding a kfree(p) into the end of error path.

2. I suggest to improve also this change description.

3. I find an other subject more appropriate.

4. I recommend to add also the label “free_port” before the missed function 
call.

   Another source code place should be accordingly adjusted then.

        ret = kobject_init_and_add(&p->kobj, &port_type,
                                   coredev->ports_kobj,
                                   "%d", port_num);
-       if (ret) {
-               kfree(p);
-               return ret;
-       }
+       if (ret)
+               goto free_port;


5. Will a similar adjustment be needed for the data structure member 
“gid_attr_group”
   according to the desired complete exception handling?
