Use DEVICE_ATTR_*() helper instead of plain DEVICE_ATTR,
which makes the code a bit shorter and easier to read.

Hi Meng

Thanks for doing what i suggested. Looks good.

Please take a look at https://docs.kernel.org/networking/netdev-FAQ.html

There are a few process issues to work out, like the branch name in
the subject, and that the merge window is currently closed so you will
need to repost next week.
