[PATCH 1/4][update] hwmon / abituguru: Use struct dev_pm_ops for power management
From: Rafael J. Wysocki

Subject: hwmon / abituguru: Use struct dev_pm_ops for power management
Make the Abit uGuru 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@xxxxxxx>

dev_get_drvdata() may be used directly instead of being wrapped in
platform_get_drvdata(to_platform_device()).
