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
