Replace the deprecated[1] use of a 1-element array in struct mpi3_event_data_pcie_topology_change_list with a modern flexible array. Additionally add __counted_by annotation since port_entry is only ever accessed in loops controlled by num_entries. For example: for (i = 0; i < event_data->num_entries; i++) { handle = le16_to_cpu(event_data->port_entry[i].attached_dev_handle); No binary differences are present after this conversion.
