The patch titled
Subject: rtc: rtc-puv3: convert puv3_rtc_driver to dev_pm_ops
has been removed from the -mm tree. Its filename was
rtc-rtc-puv3-convert-puv3_rtc_driver-to-dev_pm_ops.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Jingoo Han <jg1.han@xxxxxxxxxxx>
Subject: rtc: rtc-puv3: convert puv3_rtc_driver to dev_pm_ops
Instead of using legacy suspend/resume methods, using newer dev_pm_ops
structure allows better control over power management.
