patch "thunderbolt: make tb_bus_type const" added to usb-testing

This is a note to let you know that I've just added the patch titled

thunderbolt: make tb_bus_type const

to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git

Subject: thunderbolt: make tb_bus_type const

Now that the driver core can properly handle constant struct bus_type, move the tb_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
