Good catch!
Previously the device created was
/sys/class/remoteproc/remoteproc0/remoteproc0#vdev0buffer/
So with your fix it become something like
/bus/platform/devices/rproc-virtio.2.auto
This works fine on my platform, also when creating two virtio devices for one
remoteproc device.
Just a remark, could be nice to indicate in the commit message the result of
your patch, means the name of the files created.
With that:
