  checkpatch: Detect newlines in error_report and other error functions
  error: Consistently name Error * objects err, and not errp
  s390/sclp: Simplify control flow in sclp_realize()
  hw/s390x: Rename local variables Error *l_err to just err
  error: Clean up errors with embedded newlines (again)
  vhdx: Fix "log that needs to be replayed" error message
  pci-assign: Clean up "Failed to assign" error messages
  vmdk: Clean up "Invalid extent lines" error message
  vmdk: Clean up control flow in vmdk_parse_extents() a bit
  error: Strip trailing '\n' from error string arguments (again)
  qemu-io qemu-nbd: Use error_report() etc. instead of fprintf()
  migration: Use error_reportf_err() instead of monitor_printf()
  spapr: Use error_reportf_err()
  error: Use error_prepend() where it makes obvious sense
  error: Use error_reportf_err() where it makes obvious sense
  error: Don't decorate original error message when adding to it
  error: New error_prepend(), error_reportf_err()
