Add it. This is needed to undo the 'irq_of_parse_and_map() call from the probe function and already part of the error handling path of the probe function. It was added in the probe function only in commit d3f620b2c4fe ("fsldma: simplify IRQ probing and handling") Fixes: 77cd62e8082b ("fsldma: allow Freescale Elo DMA driver to be compiled as a module") Signed-off-by: Christophe JAILLET Link: https://lore.kernel.org/r/20201212160516.92515-1-christophe.jaillet@wanadoo.fr Signed-off-by: Vinod Koul Signed-off-by: Sasha Levin --- drivers/dma/fsldma.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/dma/fsldma.c b/drivers/dma/fsldma.c index 1117b5123a6fc..e3412be957122 100644 --- a/drivers/dma/fsldma.c +++ b/drivers/dma/fsldma.c @@ -1318,6 +1318,7 @@ static int fsldma_of_remove(struct platform_device *op) if (fdev->chan[i]) fsl_dma_chan_remove(fdev->chan[i]); } + irq_dispose_mapping(fdev->irq); iounmap(fdev->regs); kfree(fdev);
