cppcheck reports a false positive: sound/soc/codecs/da732x.c:1161:25: warning: Either the condition 'indiv<0' is redundant or there is division by zero at line 1161. [zerodivcond] fref = (da732x->sysclk / indiv); ^ sound/soc/codecs/da732x.c:1158:12: note: Assuming that condition 'indiv<0' is not redundant if (indiv < 0) ^ sound/soc/codecs/da732x.c:1161:25: note: Division by zero fref = (da732x->sysclk / indiv); ^ The code is awfully convoluted/confusing and can be simplified with a single variable and the BIT macro.
