I think this would be more appropriate: diff --git a/drivers/dma/ti/k3-udma.c b/drivers/dma/ti/k3-udma.c index ce8b80bb34d7..7f8737da3613 100644 --- a/drivers/dma/ti/k3-udma.c +++ b/drivers/dma/ti/k3-udma.c @@ -4774,6 +4774,8 @@ static int bcdma_setup_resources(struct udma_dev *ud) irq_res.desc[i].num = rm_res->desc[i].num; } } + } else { + i = 0; } if (ud->tchan_cnt) { rm_res = tisci_rm->rm_ranges[RM_RANGE_TCHAN];
