The reason why I went with just dev_name() was such that the workqueue
name and the device nodes under /sys would strictly match, which helps
as an user, and also it avoided the temporary buffer and its size
limitations. However I don't have a strong feeling about this. Sudeep, I
can confirm that:

works as well for me:
