This caused a compile warning:
  sound/usb/format.c: In function ‘parse_audio_format_rates_v2v3’:
  sound/usb/format.c:337:30: warning: ‘ret’ may be used uninitialized in this 
function [-Wmaybe-uninitialized]
    int nr_triplets, data_size, ret, ret_l6 = 0;
                                ^~~
                                
So I applied with a fix, keeping ret = 0 while dropping the
superfluous zero initialization for ret_l6.
