From 639291f263c14dd20938dca296ab04b535cafd37 Mon Sep 17 00:00:00 2001 From: Shuah Khan Date: Mon, 10 Feb 2014 09:12:27 -0700 Subject: macintosh/adb: Change platform power management to use dev_pm_ops Change adb platform driver to register pm ops using dev_pm_ops instead of legacy pm_ops. .pm hooks call existing legacy suspend and resume interfaces by passing in the right pm state.
