What is the contribution of Dongliang Mu to this patch? I reviewed this patch locally since this student is the first time to submit patch to the kernel mailing list. In my lab, I encourage all students to fix kernel issues. However, their patches should be reviewed by me first before sending the mailing list. > > > --- > > drivers/iio/adc/at91-sama5d2_adc.c | 6 +----- > > 1 file changed, 1 insertion(+), 5 deletions(-) > > > > diff --git a/drivers/iio/adc/at91-sama5d2_adc.c b/drivers/iio/adc/at91-sama5d2_adc.c > > index 50d02e5fc6fc..168399092590 100644 > > --- a/drivers/iio/adc/at91-sama5d2_adc.c > > +++ b/drivers/iio/adc/at91-sama5d2_adc.c > > @@ -2400,12 +2400,8 @@ static int at91_adc_probe(struct platform_device *pdev) > > st->dma_st.phys_addr = res->start; > > > > st->irq = platform_get_irq(pdev, 0); > > - if (st->irq <= 0) { > > - if (!st->irq) > > - st->irq = -ENXIO; > > - > > + if (st->irq < 0) > > return st->irq; > > - } > > > > st->per_clk = devm_clk_get(&pdev->dev, "adc_clk"); > > if (IS_ERR(st->per_clk)) > > -- > > 2.34.1 > > > -- Best regards, Dongliang Mu
