Subject: [PATCH v2 2/2] media: mediatek: amend vpu_get_plat_device() documentation
Date: Tue, 28 Oct 2025 11:04:54 +0100 [thread overview]
Message-ID: <20251028100454.4086-3-johan@kernel.org> (raw)
In-Reply-To: <20251028100454.4086-1-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).
