From b9f1b45bacb6485838e0504c312ecabc90c1e273 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 11 Jul 2012 21:25:55 +0200 Subject: [PATCH] i2c-puv3: Use struct dev_pm_ops for power management Make the PKUnity-v3 SoC I2C controller driver define its suspend callback through a struct dev_pm_ops object rather than by using a legacy PM hook in struct platform_driver. The empty resume callback is not necessary, so remove it. Signed-off-by: Rafael J.
