[Linux-stm32] linux-4.20-rc1/sound/soc/stm/stm32_sai_sub.c:343: Faulty error check

[David Binderman]

Hello there,

linux-4.20-rc1/sound/soc/stm/stm32_sai_sub.c:343]: (style) Checking if unsigned variable 'div' is less than zero.

Source code is

        div = stm32_sai_get_clk_div(sai, parent_rate, rate);
        if (div < 0)
                return div;

Suggest store return value from function in int local variable, test it
and only then assign it into an unsigned variable.

Regards

David Binderman
