[PATCH 0/2]scsi:libiscsi: Add iscsi_cls_conn device to sysfs correctly

From: Wenchao Hao

We found a NULL pointer dereference in iscsi_sw_tcp_conn_get_param(),
the root reason is we did sysfs addition wrong.

iscsi_create_conn() expose iscsi_cls_conn to sysfs while the related
resources are not initialized. So we should delay the calling of
device_add() until these resources has been initialized.

This patchset solve this issue by changing iscsi_conn_setup() and works
well for iscsi_tcp.

scsi: iscsi: Add helper functions to alloc and add iscsi_cls_conn
scsi:libiscsi: Add iscsi_cls_conn to sysfs after been initialized
