------------------------------------------------------
Subject: rtc: make rtc_update_irq callable with irqs enabled
From: Atsushi Nemoto <anemo@mba.ocn.ne.jp>

The rtc_update_irq() might be called with irqs enabled, if a interrupt
handler was registered without IRQF_DISABLED.

Use spin_lock_irqsave/spin_unlock_irqrestore instead of
spin_lock/spin_unlock.
