tty: serial: 8250-of: Do not warn on deferred probe
Deferred probe is an expected return value for clk_get() on many platforms. The driver deals with it properly, so there's no need to output a warning that may potentially confuse users. Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
