        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
