The fix per see seems correct, but, there are a few things you might
want to improve:

1) Fixes: format
Your "Fixes:" line does not follow the expected format, as detected by
checkpatch. you might want something as:

	Fixes: 1d3bb996481e ("Device tree aware EMAC driver")


2) The description can be improved. For instance, you say it is done in
probe but not in remove. Why should it be done in remove instead of
removed from probe()? That would help me to review it better, instead of
going into the code and figure it out.

Once you have fixed it, feel free to add:
