Subject: [PATCH v3 00/14] iommu: fix device leaks
Date: Mon, 20 Oct 2025 06:53:04 +0200 [thread overview]
Message-ID: <20251020045318.30690-1-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 v3
- fix mediatek use-after-free on probe deferral
- add acks and reviewed-bys from Marek, Yong and Thierry
Changes in v2
- drop omap reference sooner; remove unused pointer
- amend exynos commit message with reference to partial fix
- amend tegra commit message with reference to partial fix
- add Robin's ack
