Subject: Re: [PATCH v7 0/9] mfd: watchdog: rtc: New driver for ST's LPC IP

> [Alessandro: This just needs RTC Acks now]

Given this patch-set has been on the list for some time now and we
haven't heard from Alessandro in all that time, I'm going to just
apply the set and send out a pull-request to the other Maintainers.

No point waiting any longer IMHO.
