question about drivers/rtc/rtc-cmos.c

[Julia Lawall <julia.lawall@lip6.fr>]

The function cmos_do_probe contains the code:

		if (is_hpet_enabled()) {
                        int err;

                        rtc_cmos_int_handler = hpet_rtc_interrupt;
			err = hpet_register_irq_handler(cmos_interrupt);
                        if (err != 0) {
                                dev_warn(dev, "hpet_register_irq_handler "
                                                " failed in rtc_init().");
                                goto cleanup1;
                        }
                }

Is it intentional that the error code returned by 
hpet_register_irq_handler is put ina local variable that will not be seen 
at label cleanup1?  The return value is retval, which is 0 at this point.

thanks,
julia
