Cc: Gerd Hoffmann Subject: [Qemu-devel] [PATCH 3/9] default devices: parallel port X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: qemu-devel.nongnu.org List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Switch over parallel ports to the new default device system. Disable default parallel port for both '-parallel' and '-device isa-parallel' cases.
