Subject: [PATCH 3/3] media: mediatek: amend vpu_get_plat_device() documentation
Date: Wed, 24 Sep 2025 15:35:52 +0200 [thread overview]
Message-ID: <20250924133552.28841-4-johan@kernel.org> (raw)
In-Reply-To: <20250924133552.28841-1-johan@kernel.org>
Add a comment to the vpu_get_plat_device() documentation to make it
clear that the VPU platform device is returned with an incremented
reference count (which needs to be dropped after use).
