From 3e488c95c72ba8cbe8ab3a5c1c61f058f9e30aed Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Tue, 22 Nov 2016 22:06:00 +0100 Subject: s390/zcrypt: Convert to PM ops Switch the zcrypt bus from legacy suspend/resume callbacks to dev_pm_ops. The conversion is straight forward with the help of SIMPLE_DEV_PM_OPS(). The new dev_pm_ops based version is functionally equivalent to the legacy callbacks version. This will allow to eventually remove support for legacy suspend/resume callbacks from the kernel altogether.
