X-Received-From: 134.134.136.100 Subject: [Qemu-devel] [PATCH v2 4/4] vl: Simplify machine_parse() X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: pbonzini@redhat.com, ehabkost@redhat.com, armbru@redhat.com Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" X-Virus-Scanned: ClamAV using ClamSMTP From: Markus Armbruster Exploit that argument @name is nerver null. Check is_help_option() first, because that's what we do elsewhere. If we (foolishly!) defined a machine named "help", -machine help would now print help instead of selecting the machine named "help".
