This is a note to let you know that I've just added the patch titled iommu/fsl_pamu: Fix resource leak in fsl_pamu_probe() to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: iommu-fsl_pamu-fix-resource-leak-in-fsl_pamu_probe.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 29c0fc0173c907146f6c92c4995f596a4fc935c8 Author: Yuan Can <yuancan@xxxxxxxxxx> Date: Mon Nov 21 08:20:22 2022 +0000 iommu/fsl_pamu: Fix resource leak in fsl_pamu_probe() [ Upstream commit 73f5fc5f884ad0c5f7d57f66303af64f9f002526 ] The fsl_pamu_probe() returns directly when create_csd() failed, leaving irq and memories unreleased. Fix by jumping to error if create_csd() returns error. Fixes: 695093e38c3e ("iommu/fsl: Freescale PAMU driver and iommu implementation.")
