The commit 8234f6734c5d ("PM-runtime: Switch autosuspend over to using hrtimers") switched PM runtime autosuspend to use hrtimers and all related time accounting in ns, but missed update the struct dev_pm_info->timer_expires to u64. This causes timer_expires value to be truncated on 32bits architectures when assignment is done from u64 values:
rpm_suspend() |- dev->power.timer_expires = expires;
Hence, fix it by changing timer_expires type to u64.
