Re: [PATCH 32/36] driver core: Introduce device_move(): move a device to a new parent.

Hi Greg,

has this one been tested? I don't get it working. I always get an EINVAL
when trying to move the TTY device of a Bluetooth RFCOMM link around.

And shouldn't device_move(dev, NULL) re-attach it to the virtual device
tree instead of failing?

Regards

Marcel
