Subject: [PATCH 5.4 180/203] rtc: bd70528: Add MODULE ALIAS to autoload module

From: Matti Vaittinen <matti.vaittinen@...rohmeurope.com>

commit c3e12e66b14a043daac6b3d0559df80b9ed7679c upstream.

The bd70528 RTC driver is probed by MFD driver. Add MODULE_ALIAS
in order to allow udev to load the module when MFD sub-device cell
for RTC is added.

I'm not sure if this is a bugfix or feature addition but I guess
fixes tag won't harm in this case.
