devm_clk_get_optional() returns NULL when the optional clock is absent,
but returns an ERR_PTR when the clock provider lookup fails. Probe
currently keeps the ERR_PTR and then passes it to clk_get_rate().
Return the lookup error instead. A truly absent optional clock still
reaches the existing calibration fallback through clk_get_rate(NULL).
