phy.c has two different formats for docbook comments - some of them
are to the documented format, others with the extra blank line. Given
that correct form is without the blank line, new docbook comments
should conform to the standard format.

Thanks for checking back, you're correct. You can ignore this comment
as it won't make any difference.

Looking at phy_remove(), it wouldn't make any difference anyway, so
please keep the code as-is.
