* 'timers-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
  rtc: Limit RTC PIE frequency
  rtc: Fix hrtimer deadlock
  rtc: Handle errors correctly in rtc_irq_set_state()

Fixup trivial conflicts in drivers/rtc/interface.c due to slightly
trivially versions of the same patch coming in two different ways.
