Ondrej,
As your first series went via alsa tree, and we are close to the end of the merge window,
and assuming that Takashi didn't apply those patches on his tree, as you're re-sending it,
I think that the better is to wait for the end of the merge window, in order to allow us
to sync our development tree with 2.6.40-rc1, and then review and apply it on the top of it.
Thanks,
Mauro.
