ASoC: fsl-asoc-card: Fix build warning for maybe-uninitialized
When build fsl-asoc-card as module, there is following error: sound/soc/fsl/fsl-asoc-card.c: In function 'fsl_asoc_card_probe': >> sound/soc/fsl/fsl-asoc-card.c:547:13: warning: 'asrc_np' may be used uninitialized in this function [-Wmaybe-uninitialized] of_node_put(asrc_np); ^ vim +/asrc_np +547 sound/soc/fsl/fsl-asoc-card.c 531 if (width == 24) 532 priv->asrc_format = SNDRV_PCM_FORMAT_S24_LE; 533 else 534 priv->asrc_format = SNDRV_PCM_FORMAT_S16_LE; 535 } 536 537 /* Finish card registering */ 538 platform_set_drvdata(pdev, priv); 539 snd_soc_card_set_drvdata(&priv->card, priv); 540 541 ret = devm_snd_soc_register_card(&pdev->dev, &priv->card); 542 if (ret) 543 dev_err(&pdev->dev, "snd_soc_register_card failed (%d)\n", ret); 544 545 fail: 546 of_node_put(codec_np); > 547 of_node_put(asrc_np); 548 of_node_put(cpu_np); 549 550 return ret; 551 } 552 553 static const struct of_device_id fsl_asoc_card_dt_ids[] = { 554 { .compatible = "fsl,imx-audio-cs42888", }, 555 { .compatible = "fsl,imx-audio-sgtl5000", }, Add 'asrc_fail' branch for error jump after asrc_np initialized.
