Thanks for taking the time to make this work.  I'll review and test
these patches shortly, along with Gerd's UAS patches.

One question though: which xHCI host controller are you testing streams
on?  I ask because I know the Intel Ivy Bridge/Panther Point xHCI host
is pretty broken when it comes to streams, and I'm going to have to
disable streams for that host.  Haswell systems should work fine.
