Geert Uytterhoeven 31c4e2833f sh: clk: Fix clk_enable() to return 0 on NULL clk ... commit ff30bd6a6618e979b16977617371c0f28a95036e upstream. On SH, devm_clk_get_optional_enabled() fails with -EINVAL if the clock is not found. This happens because __devm_clk_get() assumes it can pass a NULL clock pointer (as returned by clk_get_optional()) to the init() function (clk_prepare_enable() in this case), while the SH implementation of clk_enable() considers that an error. Fix this by making the SH clk_enable() implementation return zero instead, like the Common Clock Framework does.
