s390 updates for the 5.7 merge window #2
- The rest of fallthrough; annotations conversion.
- Couple of fixes for ADD uevents in the common I/O layer.
- Minor refactoring of the queued direct I/O code.
s390/cio: generate delayed uevent for vfio-ccw subchannels
The common I/O layer delays the ADD uevent for subchannels and
delegates generating this uevent to the individual subchannel
drivers. The vfio-ccw I/O subchannel driver, however, did not
do that, and will not generate an ADD uevent for subchannels
that had not been bound to a different driver (or none at all,
which also triggers the uevent).
Generate the ADD uevent at the end of the probe function if
uevents were still suppressed for the device.
