X-Received-From: 209.132.183.28 Cc: aliguori@us.ibm.com Subject: [Qemu-devel] [PATCH 19/29] qemu-option: opt_set(): use error_set() X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.14 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org The functions qemu_opt_set() and opts_do_parse() both call opt_set(), but their callers expect QError semantics. Thus, both functions call qerro_report_err() to keep the expected semantics.
