From 6a7b3c3c465cef29d92dfc3fbbff0d958aa8be04 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 11 Jul 2012 21:27:30 +0200 Subject: [PATCH] i2c-tegra: Use struct dev_pm_ops for power management Make the Tegra I2C controller driver define its PM callbacks through a struct dev_pm_ops object rather than by using legacy PM hooks in struct platform_driver.
