Browse source

cppcheck throws the following warning:

sound/soc/soc-core.c:2773:6: style: Condition '!num_widgets' is always
false [knownConditionTrueFalse]
 if (!num_widgets) {
     ^

sound/soc/soc-core.c:2761:18: note: Assuming that condition
'num_widgets<0' is not redundant
 if (num_widgets < 0) {
                 ^
sound/soc/soc-core.c:2766:18: note: Assuming condition is false
 if (num_widgets & 1) {
                 ^
sound/soc/soc-core.c:2772:2: note: Compound assignment '/=', assigned
value is 0
 num_widgets /= 2;
 ^

We should check upfront all error conditions.
