Subject: [PATCH 1/2] drm/virtio: add virtio_gpu_object_detach() function
Date: Wed, 29 Aug 2018 14:20:25 +0200 [thread overview]
Message-ID: <20180829122026.27012-2-kraxel@redhat.com> (raw)
In-Reply-To: <20180829122026.27012-1-kraxel@redhat.com>
The new function balances virtio_gpu_object_attach().
Also make virtio_gpu_cmd_resource_inval_backing() static and switch
call sites to the new virtio_gpu_object_attach() function.
