Krzysztof pointed out cleanups only for clk_disable_unprepare() will lose the code symmetry. NULL pointer checks for clk_prepare_enable() should be removed to keep the code symmetrical. This is possible for common-clock framework because clk_prepare_enable() is also a no-op for a NULL clk input. But it is not necessarily true for non-common clock implementations. -- Best Regards Masahiro Yamada -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
