stylistically I think the commonly used pattern, where goto is only used for error handling is clearer. IIUC this change is using goto to jump to a success case continuation, while handling the error on the main code path. Also it doesn't seem to be related to the fix. The actual fix seems to be removing the lines 1579-1582 (and removing the jump label), that would also make the patch smaller

In fact the code - including the return statement - after in_fmt: label could be added here in side this if statement, and the loop would still be reasonable size. But IMO not a big deal.

right, I converted this function to work and look like the coutnerpart sof_ipc4_init_output_audio_fmt().

I can keep the two function different, but I cannot change the output function when touching the input.

}

if (i == pin_fmts_size) {
dev_err(sdev->dev,
"%s: Unsupported audio format: %uHz, %ubit, %u channels, type: %d\n",
__func__, params_rate(params), sample_valid_bits,
params_channels(params), sample_type);
return -EINVAL;
}

"%s: Unsupported audio format: %uHz, %ubit, %u channels, type: %d\n",
__func__, params_rate(params), sample_valid_bits,
params_channels(params), sample_type);

return -EINVAL;

in_fmt:
/* copy input format */
