On a PowerPC board with ds1374 RTC I'm getting this error while RTC tries
to probe:
rtc-ds1374 0-0068: unable to request IRQ
This happens because I2C probing code (drivers/of/of_i2c.c) is specifying
IRQ0 for 'no irq' case, which is correct.
The driver handles this incorrectly, though. This patch fixes it.
