commit 6b61d49a55796dbbc479eeb4465e59fd656c719c upstream.
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 to update the timer_expires
data type in struct dev_pm_info to u64.
This causes the timer_expires value to be truncated on 32-bit
architectures when assignment is done from u64 values:
rpm_suspend()
|- dev->power.timer_expires = expires;
Fix it by changing the timer_expires type to u64.
Fixes: 8234f6734c5d ("PM-runtime: Switch autosuspend over to using hrtimers")
