i40iw: Fixes for static checker warnings
Remove NULL check for cm_node->listener in i40iw_accept as listener is always present at this point. Remove the check for cm_node->accept_pend and related code in i40iw_cm_event_connected as the cm_node in this context is only pertinent to active node and cm_node->accept_pend is always 0. This fixes the following smatch warnings, drivers/infiniband/hw/i40iw/i40iw_cm.c:3691 i40iw_accept() error: we previously assumed 'cm_node->listener' could be null drivers/infiniband/hw/i40iw/i40iw_cm.c:4061 i40iw_cm_event_connected() error: we previously assumed 'cm_node->listener' could be null Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Shiraz Saleem <shiraz.saleem@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
