Hi,

In function tegra_pinctrl_dt_node_to_map the num_maps the num_maps
counter must be incremented for each child node?


Actually we are doing free until num_maps if tegra_pinctrl_dt_subnode_to_map,

not only that if num_maps == 0, we wont free up the maps, and also i
think the for_each_of_node checks whether we have a next child node,
so its safe to do num_maps++ as it wont get incremented endlessly,

Please correct me if i am wrong.

Thanks,
