hwmon: (gpio-fan) Use struct dev_pm_ops for power management
Make the gpio-fan driver define its PM callbacks through a struct dev_pm_ops object rather than by using legacy PM hooks in struct platform_driver. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> [linux@roeck-us.net: CONFIG_PM->CONFIG_PM_SLEEP, and remove unnecessary ()] Signed-off-by: Guenter Roeck <linux@roeck-us.net>
