You're kidding right?

Please read Documentation/stable_kernel_rules.txt.  How do all of these
patches relate to that file?

For adding support for new devices, I'll take patches that just add a
new id, but for a series like this, no.  Just use the 3.3 kernel
release, what's wrong with that?  3.2-stable is about to be dropped in a
week or so anyway.

thanks,
