Since "struct rtc_device" is per a device struct, I assume that clear_uie()
needs to wait for only one work associated with that device. Therefore,
wait for only that work using flush_work().

Please see commit c4f135d643823a86 ("workqueue: Wrap flush_workqueue()
using a macro") for background.
Changes in v4:
Use flush_work() instead of introducing a dedicated WQ.
