Geert Uytterhoeven ff30bd6a66 sh: clk: Fix clk_enable() to return 0 on NULL clk ... 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.
