PM / crypto / ux500: Use struct dev_pm_ops for power management
Make the ux500 crypto driver define its PM callbacks through struct dev_pm_ops objects rather than by using legacy PM hooks in struct platform_driver. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Linus Walleij <linus.walleij@linaro.org>
