From 62fcbdd95ccabcff7b41a859032496f6ca492045 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 27 Jun 2012 23:26:07 +0200 Subject: ACPI: Use struct dev_pm_ops for power management in the fan driver Make the ACPI fan driver define its PM callbacks through a struct dev_pm_ops object rather than by using legacy PM hooks in struct acpi_device_ops.
