Here a couple updates to the vfio-ccw traces in the kernel,
based on things I've been using locally. Perhaps they'll
be useful for future debugging.

v2 -> v3:
- Added Conny's r-b to patches 1, 2, 4
- s/command=%d/command=0x%x/ in patch 3 [Cornelia Huck]

v1/RFC -> v2:
- Convert state/event=%x to %d [Steffen Maier]
- Use individual fields for cssid/ssid/sch_no, to enable
filtering by device [Steffen Maier]
- Add 0x prefix to remaining %x substitution in existing trace

Eric Farman (4):
vfio-ccw: Refactor how the traces are built
vfio-ccw: Trace the FSM jumptable
vfio-ccw: Add a trace for asynchronous requests
vfio-ccw: Rework the io_fctl trace
