Ah, please add a comment about that. It could be there is a minor
design issue within the PHY, and this is their workaround. So keep
it. A comment will then stop reviewers like me asking...

Part of producing a good patch is to try to think of all the questions
reviewers will ask, and answer them as part of the patch. Either
comments in the code, to text in the commit message.
