From 1e280c8d610603571a27f09d9b3ee215c2e0d869 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 12 Dec 2020 17:05:16 +0100 Subject: dmaengine: fsldma: Fix a resource leak in the remove function [ Upstream commit cbc0ad004c03ad7971726a5db3ec84dba3dcb857 ] A 'irq_dispose_mapping()' call is missing in the remove function. 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(+) (limited to 'drivers/dma') diff --git a/drivers/dma/fsldma.c b/drivers/dma/fsldma.c index 2209f75fdf05..1a637104cc08 100644 --- a/drivers/dma/fsldma.c +++ b/drivers/dma/fsldma.c @@ -1436,6 +1436,7 @@ 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); -- cgit v1.2.3
