I don't believe this is an urgent issue. The issue has existed since MT7531 support was added in September 2020, and no one has raised it as a problem until I identified the clearly incorrect expression. What if fixing this unmasks a problem elsewhere? Therefore, I see no reason to rush getting this fix into the -rc kernel, especially without a review and preferably testing by the driver authors.

Discussing one of the tests in mt753x_phylink_validate() with Landen Chao confirms that the "||" should be "&&". Fix this.
