Hi!
My preference would be to not wrap the quoted text. To hell with
warnings about long lines for cases like this. However, I'm not
going to require a new iteration for that detail, but keep that
in mind for the next patch or if you end up resending for some
unrelated reason.

This driver will not be the first to select I2C_MUX. So, even if it
it is a bit untidy to select stuff that is also selectable by the
user...
