Subject: [PATCH v2 0/2] media: mediatek: fix VPU device leaks on probe
Date: Tue, 28 Oct 2025 11:04:52 +0100	[thread overview]
Message-ID: <20251028100454.4086-1-johan@kernel.org> (raw)

This series fixes VPU device leaks during probe of the mdp driver.

Included is also a minor documentation update to make it clear that the
VPU lookup helper returns the device with an incremented refcount.

Johan


Changes in v2
 - drop incorrect vcodec patch since that reference leak has already
   been fixed by commit bf1d556ad4e0 ("media: mtk-vcodec: abstract
   firmware interface") which added the codec release callback
