It's the middle of the merge window right now, there's nothing I can do
with this until after it is over. Please wait until then to expect a
response, and even then, give me a week or so to dig out from under the
pending-patch load.

You shouldn't ask Greg and me; you should ask the Freescale maintainer.
He is the person who has to approve your patches.
