+ pinctrl = devm_pinctrl_get_select_default(&pdev->dev); + if (IS_ERR(pinctrl)) + dev_warn(&pdev->dev, "failed to configure pins from driver\n");I think we already discussed this, but shouldn't this be a fatal error?I had checked relevant discussion and found this can be warning message. This is because most boards don't have pinctrl implemented at this point, or may never have. https://lkml.org/lkml/2012/9/11/369 Any way I will change to dev_warn(&pdev->dev, "unable to select pin group\n"); as in other drivers.
But in case pinctrl isn't implemented, shouldn't the implementation of devm_pinctrl_get_select_default() just be a no-op? Thierry
