No, I haven't done this test, because my environment didn't change when testing the two different kernel versions.
Nevertheless I have added the printk() calls starting with the string 'afrie:' in cmos_alarm_irq_enable() and cmos_set_alarm(). The console output was captured by a second PC via serial line:
When booting there are no extra log messages (see boot.log).
Wenn calling 'init 0' there are 3 extra messages. I have tested it with and without your patch (refer to init_0_with_patch.log and init_0_without_patch.log). The last one is always a 'disable' message but I found the following difference: In the 'patched' case the disable message comes from cmos_alarm_irq_enable(). In the other case the disable message comes from cmos_set_alarm(). May be you can explain what's going on?
