[PATCH 3/4] rtc: rtc-twl: Remove lockdep related local_irq_enable()

From: John Stultz
Date: Wed Aug 10 2011 - 19:03:04 EST

From: Sebastian Reichel <sre@xxxxxxxxxx>

Now that the irq is properly threaded (due to it needing i2c access)
we should also remove the local_irq_enable() call in twl_rtc_interrupt.
Testing this with Pandaboard, the RTC is still working.
