PM: Add convenience macro to make switching to dev_pm_ops less error-prone
In a number of cases, the .suspend, .freeze, .poweroff and .resume, .thaw, .restore functions are identical. However, they all need to be assigned to avoid regressionsm as the previous code called .suspend resp. .resume in all those cases. SIMPLE_DEV_PM_OPS helps to deal with this case. [rjw: Changed the name of the macro and added the comment explaining its purpose.] Signed-off-by: Albin Tonnerre <albin.tonnerre@free-electrons.com> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
