Subject: [PATCH 0/2][RFC] Try to handle hctosys w/ rtc modules 

Its been pointed out that the RTC hctosys functionality doesn't
work well with RTC modules, which may not be loaded until after
late_init().

While there have been other attempts to sovle this, this patchset
is a very quick 10 minute effort to show how I'd try to resolve
this. There likely are still issues here, but I'd be happy to
make fixes and adjustments to ensure it works.

Feedback and comments always appreciated!
