Hi Greg,
Here's a couple of fixes for the xHCI driver. Three patches are nothing
major: build warning fix, macro field width fix, and removing some
unnecessary log spam.
The only interesting thing here is Tianyu's two patches to fix the USB
port connection type discovery, for the USB port power off mechanism.
This adds new USB host API, but as discussed, it's necessary to avoid
powering off the wrong USB port. It's not marked for backport to stable
kernels, since the sysfs mechanism to manually power off a port didn't
go in until 3.9.
I've smoke tested these, including system suspend, USB device suspend,
and rocking out in my cube with a pair of USB headphones. They look
fine to me.
Hibernate is currently broken on my system, due to some nouveau MMIO
read faults. I'll report that separately.
