It bisected down to this:
commit a2582bd478c13c574d4c16ef1209d333f2a25935

USB: Close usb_find_interface race
USB drivers that create character devices call usb_register_dev in their
probe function. This associates the usb_interface device with that minor
number and creates the character device and announces it to the world.
However, the driver's probe function is called before the new
usb_interface is added to the driver's klist_devices.
...
and what's even scarier is that that commit is marked for stable too. Did
it already make it?
I'll double-check by reverting it from current -tip, but if you don't hear
anything different from me, you can assume that that double-check
succeeded and confirms that that commit really is the cause of my printer
no longer working.
