Subject: [PATCH] qemu: consolidate parameters of qemuBuildChrChardevStr into
flags
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
https://bugzilla.redhat.com/show_bug.cgi?id=1597940
There are two boolean parameters passed to qemuBuildChrChardevStr,
and soon there will be a third. It will be clearer to understand
from callers' POV if we use named flags instead.
Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
(cherry picked from commit 0140d4c59b7fb26432b520bb7e85bd6834f560b0)
