Might be out of scope, but since we removed one redundant "db_count"
variable already, perhaps we could also drop this one, too.  Just to add
a small clean-up since we are touching this code already...  Thoughts?

Looking at epf_ntb_db_mw_bar_init():

  (...)

  db_count = ntb->db_count;

  for (bar = BAR_DB_MW1, i = 0; i < num_mws; bar++, i++) {
        if (bar == BAR_DB_MW1) {
                align = align ? align : 4;
                size = db_count * align;
                size = ALIGN(size, ntb->mws_size[i]);
                ctrl = ntb_epc->reg;
                ctrl->mw1_offset = size;
                size += ntb->mws_size[i];
        } else {
                size = ntb->mws_size[i];
        }

        (...)
  }

Thank you!
