[Qemu-devel] [PATCH v5 1/5] qdev: add description field in PropertyInfo


From: arei.gonglei
Subject: [Qemu-devel] [PATCH v5 1/5] qdev: add description field in PropertyInfo struct
Date: Tue, 7 Oct 2014 14:33:20 +0800

From: Gonglei <address@hidden>

The descriptions can serve as documentation in the code,
and they can be used to provide better help.
