Your subject, and body of text, seem to have 2 "odd" characters in it,
please fix up.

Also, your subject and changelog body here are identical, please be much
more verbose in the body explaining why you are doing something, not
just what you are doing.

And your subject line should also match other patches for this file, and
have "usb: phy: ..." in the beginning.

Why isn't the compiler complaining about this today? Are you sure this
is needed?
