Subject: rtc-m48t59 driver NO_IRQ mode fixup
From: Mark Zhan <rongkai.zhan@windriver.com>

Since irq in m48t59_private struct is defined as 'unsigned int', which will
make the following if sentence to be never true:

         if (m48t59->irq < 0)
                  m48t59->irq = NO_IRQ;

And thus it will make the m48t59_rtc_probe() is failed when the driver is
working in a no irq mode:
