Subject: Re: [RFC 08/17] ARM: mvebu: remove custom .init_time hook
Hi Sebastian,
I've only received a few patches of this series. I *think*
using "RFC" alone is not correct in LAKML and for some reason
you're required to use RFC/PATCH.
Maybe that's why I'm getting only the patches where I'm Cced?
Could you please re-send this? The series looks promising and I'd like
to take a peep :-)
BTW, some of this (but not all) has already been posted [1, 2] and
is on its way to v3.12 through Daniel Lezcano.
(Maybe you already noticed, but just in case...)
