[Qemu-devel] [PULL 1/3] usb: replace handle_destroy with unrealize

[Gerd Hoffmann]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Curiously, unrealize() is not being used, but it seems more
appropriate than handle_destroy() together with realize(). It is more
ubiquitous destroy name in qemu code base and may throw errors.

[Qemu-devel] [PULL 2/3] usb: ohci: fix error return code in servicing td

[Gerd Hoffmann]

From: Li Qiang <liq3ea@gmail.com>

It should return 1 if an error occurs when reading td.
This will avoid an infinite loop issue in ohci_service_ed_list.

[Qemu-devel] [PULL 3/3] xhci: properties cleanup

[Gerd Hoffmann]

Split xhci properties into common and nec specific.

Move the backward compat flags to nec, so the new qemu-xhci
devices doesn't carry on the compatibiity stuff.

Move the msi/msix switches too and just enable msix for qemu-xhci.

Also move the intrs and slots properties.  Wasn't a great idea to
make them configurable in the first place, nobody needs this.
