The idea is _not_ to register them on boards that only have a single RS232 connector. The fix was just having the 8250 code understand that it should only register ports that are real. > If you wish to have three ports in an plat_serial8250_port array, you'll > need to ensure that CONFIG_SERIAL_8250_NR_UARTS is set to at least 3. That is, there's no third way which (a) doesn't waste that memory, and (b) doesn't produce annoying messages about non-error cases? ISTR that having NR_UARTS bigger just produced different messages... - Dave - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
