Subject: [PATCH 00/15] dmaengine: fix device leaks
Date: Mon, 17 Nov 2025 17:12:42 +0100	[thread overview]
Message-ID: <20251117161258.10679-1-johan@kernel.org> (raw)

The dmaengine drivers pretty consistently failed to release references
taken when looking up devices using of_find_device_by_node() and similar
helpers.

Included are also two OF node leak fixes and a couple of related
cleanups.
