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.
