My static checker complains that "resp" could be unitialized on error when we print its value.

The 'resp' variable is firstly given to snd_mixart_send_msg().
static int mixart_update_monitoring(struct snd_mixart* chip, int channel) { ... err = snd_mixart_send_msg(chip->mgr, &request, sizeof(resp), &resp); if((err<0) || resp) { dev_dbg(chip->card->dev, "error MSG_CONNECTOR_SET_OUT_AUDIO_LEVEL card(%d) resp(%x)\n", chip->chip_idx, resp); return -EINVAL; } return 0; }
When the function, snd_mixart_send_msg(), assigns nothing to the variable in error cases, dev_dbg() prints uninitialized value.
