Paolo recently suggested "to move the bus argument (and thus
qdev_set_parent_bus) to qdev_init"[1], and that it "would be quite
large but hopefully scriptable"[2].  Nerd sniped!

The series is big, but at least the bigger patches are all mechanical.

It is based on my "[PATCH v3 00/24] Fixes around device realization".

I'm abstaining from cc'ing maintainers on mechanical conversions.  I
still cc: for patches I deem interesting, with related patches thrown
in for context.  Let me know if you think I should cc: more widely.

PATCH 01-03  	Preliminary cleanup
PATCH 04     	New qdev infrastructure
      	     	Commit message explains why the current state is
      	     	problematic, and how my work improves it.
PATCH 05-12  	Convert direct users of qdev
PATCH 13-17  	Convert PCI
PATCH 18-21  	Convert ISA
PATCH 22-25  	Convert SSI
PATCH 26-29  	Convert USB
PATCH 30     	Garbage collection
PATCH 31-34  	Convert aux-bus
PATCH 35-42  	Clean up around child device initialization
PATCH 43-52  	Convert sysbus
PATCH 53     	Stop pretending recursive realization is about to become
      	     	real
PATCH 54-56  	Convert bus-less devices
PATCH 57	Garbage collection
PATCH 58	Maintain MAINTAINERS

Enjoy!

v3:
* Rebased; noteworthy conflicts
  - PATCH 36+48+56: commit fe0fe4735e7 (new machine opentitan)
  - PATCH 47: commit 26cd0362dd4 (machines spike_v1.9.1 and
    spike_v1.10 are gone)
  - PATCH 48: commit 60bf734e64 and 3d46938bbb (new bmc2835
    children)
  - PATCH 48: v3 of "macio: Fix to realize "mos6522-cuda" and
    "mos6522-pmu" devices"
  Puh!
* PATCH 08: Coccinelle script in commit message fixed; patch unchanged
* PATCH 19: Two coding style fixes

v2:
* Rebased
* PATCH 02+03:
  Old PATCH 02 is actually a revert, replace by propert reverts
  [Philippe]
* PATCH 04:
  - Fix pasto [Alistair]
  - Rephrase qdev_realize_and_unref()'s contract [Paolo]
  - qdev_realize() passes on realize error unprefixed (because
    prefixes can pile up)
* PATCH 08:
  Drop unwanted code motion [Paolo]
* PATCH 09:
  - Make the Coccinelle script safer; output unchanged [Paolo]
  - Delete a Coccinelle rule that due to rebase applies just once;
    move its code changes (hw/char/serial.c, hw/display/ati.c,
    half of hw/display/sm501.c) to the next patch
  - Move changes to hw/arm/highbank.c to next patch, where they belong
* PATCH 31:
  New [Philippe]
* PATCH 32:
  Rename aux_realize_bus() to aux_bus_realize() [Philippe]
* PATCH 47:
  &dev->parent_obj doesn't work after rebase, use SYS_BUS_DEVICE(dev)
  instead
* PATCH 52:
  New [Philippe]
* PATCH 53:
  Clean up on realize error [David]
* PATCH 54:
  Don't restrict qdev_realize_and_unref() to non-null bus [Paolo]
