serial: goldfish: return error when device address is invalid

2026-06-23T18:37:21Z

goldfish_serial_of_to_plat() returns success even when dev_read_addr() fails to find a valid address. This leaves plat->reg unset and defers the failure to probe(). Return -EINVAL immediately when the address is FDT_ADDR_T_NONE so the failure is reported at the of_to_plat stage where it belongs. Signed-off-by: Naveen Kumar Chaudhary Acked-by: Kuan-Wei Chiu
