[PATCH 6.0 0794/1073] iommu/fsl_pamu: Fix resource leak in fsl_pamu_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Yuan Can <yuancan@xxxxxxxxxx>

[ 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.
