If the packet contains a\nnegative or out-of-range channel number, the driver may write past\nthe end of these arrays.\n\nIntroduce a local channel variable and validate it before updating the\narrays. We reject negative indices, limit meter_level[] and\ncomp_level[] to SND_US16X08_MAX_CHANNELS, and guard master_level[]\nupdates with ARRAY_SIZE(master_level)."
