[PATCH 22/24] qemu: Use qemuBuildChrChardevCommand for vhost-user-gpu backend chardev
Peter Krempa

Thu Dec 9 12:30:57 UTC 2021
Now that the API for qemuBuildChrChardevCommand is sane enough, we can
use it to centralize formatting of '-chardev' generally.
The 'virDomainVideoDef' doesn't use 'virDomainChrSourceDef' internally so
we create it for this occasion manually.
