From 696160fec162601d06940862b5b3aa4460344c1b Mon Sep 17 00:00:00 2001 From: John Stultz Date: Thu, 3 Feb 2011 12:02:07 -0800 Subject: RTC: Cleanup rtc_class_ops->irq_set_freq() With the generic rtc code now emulating PIE mode irqs via an hrtimer, no one calls the rtc_class_ops->irq_set_freq call. This patch removes the hook and deletes the driver functions if no one else calls them.
