From: Eric Blake Date: Thu, 28 Apr 2016 21:45:13 +0000 (-0600) Subject: qapi: Consolidate QMP input visitor creation X-Git-Tag: TizenStudio_2.0_p4.0~6^2~12^2~6^2~274^2~18 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fc471c18d5d2ec713d5a019f9530398675494bc8;p=sdk%2Femulator%2Fqemu.git qapi: Consolidate QMP input visitor creation Rather than having two separate ways to create a QMP input visitor, where the safer approach has the more verbose name, it is better to consolidate things into a single function where the caller must explicitly choose whether to be strict or to ignore excess input. This patch is the strictly mechanical conversion; the next patch will then audit which uses can be made stricter.
