This is a note to let you know that I've just added the patch titled
xhci-pci: Allow host runtime PM as default for Intel Maple Ridge xHCI
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-testing branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will be merged to the usb-next branch sometime soon,
after it passes testing, and the merge window is open.
If you have any questions about this process, please let me know.

Subject: xhci-pci: Allow host runtime PM as default for Intel Maple Ridge xHCI
Intel Maple Ridge is successor of Titan Ridge Thunderbolt controller. As
Titan Ridge this one also includes xHCI host controller. In order to
safe energy we should put it to low power state by default when idle.
For this reason allow host runtime PM for Maple Ridge.
