The quick exit check of (mode == MODE_SINGLE_CHAN) results in coverity reporting a logically dead code issue in the switch code in labpc_ai_check_chanlist().Remove the quick exit check and allow the function to handle the MODE_SINGLE_CHAN normally (the for loop will only happen 1 time and the function will return 0).
