[Qemu-devel] [PULL v3 06/28] qobject: Drop useless QObject casts

[Markus Armbruster <armbru@redhat.com>]

From: Eric Blake <eblake@redhat.com>

We have macros in place to make it less verbose to add a subtype
of QObject to both QDict and QList. While we have made cleanups
like this in the past (see commit fcfcd8ffc, for example), having
it be automated by Coccinelle makes it easier to maintain.

Patch created mechanically via:
  spatch --sp-file scripts/coccinelle/qobject.cocci \
    --macro-file scripts/cocci-macro-file.h --dir . --in-place
then I verified that no manual touchups were required.
