rtc: rtc-twl: Remove lockdep related local_irq_enable()
Sebastian Reichel [Tue, 31 May 2011 08:51:39 +0000 (08:51 +0000)]
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.
