Hello,

Some positive news. There will be no next version, as Qualcomm is going
to provide a superior patchset that I tested. It's easier to backport,
cleaner design, fewer lines changed, has 1 author as opposed to 3, and
most importantly, it worked just fine on my 2x card setup. 

Thus, I'm going to abandon this patchset.
