Your patch looks fine, and I'll apply it to my usb-next branch later
this week.

However, can you please send future patches to
sarah.a.sharp@xxxxxxxxxxxxxxx, not my intel.com address?  The intel.com
one runs through a horrible exchange server that converts tabs to spaces
and makes it impossible to apply patches.

Where did you find the intel.com email address?  I'm pretty sure the
MAINTAINERS file lists the linux.intel.com one, and I'd like to make
sure people aren't getting bad information.
