[Qemu-devel] [PATCH 0/7] Fix device introspection regressions

[Markus Armbruster]

QMP command device-list-properties regressed in 2.1: it can crash or
leave dangling pointers behind.

-device FOO,help regressed in 2.2: it no longer works for
non-pluggable devices.  I tried to fix that some time ago[*], but my
fix failed review.  This is my second, more comprehensive try.

PATCH 1,2 are preliminaries, PATCH 3 adds tests to demonstrate the
bugs, PATCH 4-6 fix them to a degree (see PATCH 5 for limitations),
and PATCH 7 cleans up.

[*] [PATCH] qdev: Make -device FOO,help help again when FOO is not
pluggable
