| Message-ID | <qVMnx-6eG-17@gated-at.bofh.it> |
It would be broken if stm_data->sw_start isn't zero, because that stp_master_free() get the 'master' with __stm_master()/stm_master(), in which the masterID is the second input parameter minus stm_data->sw_start. So freeing STM masters has to start from stm_data->sw_start.
