[PATCH 44/59] rtc: rs5c372: stop using deprecated RTC API

From: Bartosz Golaszewski
Date: Thu Nov 19 2020 - 06:44:40 EST


From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

devm_rtc_device_register() is deprecated. Use devm_rtc_allocate_device()
and devm_rtc_register_device() pair instead.

While at it: remove unnecessary label.
