Not me, Sean. My original implementation of phylink_validate_mask_caps()
doesn't know anything about rate matching, so my version didn't have
this issue.

Sean's version of my patch (which is what was submitted) added the
dereference that causes this, so, it's up to Sean to figure out a fix -
but he reading his follow up to the build bot's message, he seems to
be passing it over to me to fix!

I've got other issues to be worked on right now, and have no time to
spare to fix other people's mistakes. Sorry.

You can't always rely on the apparent author mentioned in the commit to
be the actual person responsible for the changes in a patch.
