What his the status of the patch? Has it been reviewed and taken in an
integration tree? I cannot find anything about it in l-o and
linux-next.

I have some changes on-going in the OMAP PM code and I would like to
know if $SUBJECT is applicable.

Regards,
Jean

Hi Jean,

My bad, I didn't follow up with this. My guess is that it has not been
