Subject: rtc-dev: no need to convert file->private_data to rtc device
From: Mark Zhan <rongkai.zhan@xxxxxxxxxxxxx>
In rtc-dev.c, when a rtc device is opened, file->private_data is already
attached with the rtc device pointer, so there is no need to call
to_rtc_device() to convert file->private_data to a rtc device pointer.
