Date: Wed, 10 Aug 2011 16:01:57 -0700 From: John Stultz <john.stultz@...aro.org> To: LKML <linux-kernel@...r.kernel.org> Cc: Sebastian Reichel <sre@...ian.org>, Thomas Gleixner <tglx@...utronix.de>, John Stultz <john.stultz@...aro.org> Subject: [PATCH 3/4] rtc: rtc-twl: Remove lockdep related local_irq_enable() From: Sebastian Reichel <sre@...ian.org> 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.
