From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit 7079b3483a17be2cfba64cbd4feb1b7ae07f1ea7 ]
If device_register() fails, device_unregister() should not be called
because it will free some resources that are not allocated.
put_device() should be used instead.
Fixes: 308ee87a2f1e ("staging: fieldbus: anybus-s: support HMS Anybus-S bus")
