 "Second round of s390 fixes and features for 5.7:

   - 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"

* tag 's390-5.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
  s390/cio: generate delayed uevent for vfio-ccw subchannels
  s390/cio: avoid duplicated 'ADD' uevents
  s390/qdio: clear DSCI early for polling drivers
  s390/qdio: inline shared_ind()
  s390/qdio: remove cdev from init_data
  s390/qdio: allow for non-contiguous SBAL array in init_data
  zfcp: inline zfcp_qdio_setup_init_data()
  s390/qdio: cleanly split alloc and establish
  s390/mm: use fallthrough;
