  "message": "qom: Fix invalid error check in property_get_str()\n\nWhen a function returns a null pointer on error and only on error, you\ncan do\n\n    if (!foo(foos, errp)) {\n        ... handle error ...\n    }\n\ninstead of the more cumbersome\n\n    Error *err \u003d NULL;\n\n    if (!foo(foos, \u0026err)) {\n        error_propagate(errp, err);\n        ... handle error ...\n    }\n\nA StringProperty\u0027s getter, however, may return null on success!  We\nthen fail to call visit_type_str().\n\nScrewed up in 6a146eb, v1.1.\n\nFails tests/qom-test in my current, heavily hacked QAPI branch.  No\nreproducer for master known (but I didn\u0027t look hard).\n\nCc: Anthony Liguori \u003canthony@codemonkey.ws\u003e\nSigned-off-by: Markus Armbruster \u003carmbru@redhat.com\u003e\nReviewed-by: Eric Blake \u003ceblake@redhat.com\u003e\nCc: qemu-stable@nongnu.org\nSigned-off-by: Andreas Färber \u003cafaerber@suse.de\u003e\n",
