[patch] iommu/vt-d: returning free pointer in get_domain_for_dev()

If we hit this error condition then we want to return a NULL pointer and not a freed variable. Signed-off-by: Dan Carpenter dan.carpen...@oracle.com diff --git a/drivers/iommu/intel-iommu.c b/drivers/iommu/intel-iommu.c index 6fbce01..69fa7da 100644 --- a/drivers/iommu/intel-iommu.c +++

[PATCH 0/5] Renesas VMSA-compatible IPMMU DT support

Hello, This patch set adds DT support to the Renesas VMSA-compatible IPMMU driver. The first patch refactors the driver to remove dependencies on platform data, the second patch adds the DT bindings documentation and the third patch implement them in the driver. The next two patches show

[PATCH 1/5] iommu/ipmmu-vmsa: Refactor micro-TLB lookup

Cache the micro-TLB number in archdata allocated in the .add_device handler instead of looking it up when the deviced is attached and detached. This simplifies the .attach_dev and .detach_dev operations and prepares for DT support. Signed-off-by: Laurent Pinchart
