The reason is that the phyaddr of the top ext register is 9, so max_ports should be used for the check to include it. 4) In the yt922x driver, added initialization of yt921x_port for exporting priv. changes in v7: patch 1: Fix the series_lookup() redundancy issue. Fix the dsa->priv initialization and the code style issue. patch 6: Move psc definition to yt921x_port Fix psc_get_state() and an_restart(). Use the existing yt921x driver interface for the duplicated logic for chip_reset(). Move the yt922x_cpu_port_set() to chip_setup_dsa() to align with yt921x function.
