Subject: [PATCH v2 00/14] iommu: fix device leaks
Date: Tue, 7 Oct 2025 11:43:13 +0200 [thread overview]
Message-ID: <20251007094327.11734-1-johan@kernel.org> (raw)
This series fixes device leaks in the iommu drivers, which pretty
consistently failed to drop the reference taken by
of_find_device_by_node() when looking up iommu platform devices.
Included are also a couple of related cleanups.
Johan
Changes in v2
- drop omap reference sooner; remove unused pointer
