Ok, next time I want to see some QCOM engineers to sign off on this that
it was actually tested and they can back it up that this is ready to be
merged.  When the code doesn't even build, that is a huge red flag that
this whole thing is being rushed as it obviously was never tested in the
form that was submitted for inclusion.

You all know better than this.
