[Qemu-devel] [PATCH 04/12] chardev: remove many local variables in qemu_


From: Daniel P . Berrangé
Subject: [Qemu-devel] [PATCH 04/12] chardev: remove many local variables in qemu_chr_parse_socket
Date: Tue, 15 Jan 2019 14:52:48 +0000

Now that all validation is separated off into a separate method,
we can directly populate the ChardevSocket struct from the
QemuOpts values, avoiding many local variables.
