| |
When a I3C DT node has a static_addr and an init_dyn_addr,the init_dyn_addr is reserved in i3c_master_bus_init() and then the static_addr is reserved in i3c_master_early_i3c_dev_add(). But if the dynamic address is same as static then above procedure would fail. Add a check to pass i3c_bus_get_addr_slot_status() when static and dynamic address are equal.
