From: John Stultz Date: Thu, 3 Feb 2011 20:13:50 +0000 (-0800) Subject: RTC: Cleanup rtc_class_ops->update_irq_enable() X-Git-Tag: firefly_0821_release~7613^2~2235^2~6 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=51ba60c5bb3b0f71bee26404ddc22d8e4109e88a;p=firefly-linux-kernel-4.4.55.git RTC: Cleanup rtc_class_ops->update_irq_enable() Now that the generic code handles UIE mode irqs via periodic alarm interrupts, no one calls the rtc_class_ops->update_irq_enable() method anymore. This patch removes the driver hooks and implementations of update_irq_enable if no one else is calling it.
