From 1928bb57387d1fcca51c2ea08b9d856515f382e4 Mon Sep 17 00:00:00 2001 From: Shuah Khan Date: Fri, 28 Jun 2013 09:53:43 +1000 Subject: [PATCH] drivers/rtc/class: convert from Legacy pm ops to dev_pm_ops Convert drivers/rtc/class to use dev_pm_ops for power management and remove Legacy PM ops hooks. With this change, rtc class registers suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy class->suspend/resume. When __device_suspend() runs call-backs, it will find class->pm ops for the rtc class.
