This fixes an xhci regression (soft lockup at boot under VirtualBox), which is
caused by a cc-stable patch[0] from mainline v4.7-rc4.  The lockup is
reproducible with all kernels which include that patch, including Xenial and
Yakkety.  I'll submit this upstream with cc-stable, pending ACK approval here.
