6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ming Qian <ming.qian@xxxxxxx>
[ Upstream commit 73e3f09292a0492a3fe0f87a8170a74f12624c5e ]
according to v4l2 stateful decoder document 4.5.1.3. State Machine,
the state should change from seek to initialization
if call VIDIOC_REQBUFS(OUTPUT, 0).
so reinit the vpu decoder if reqbufs output 0
Fixes: 6de8d628df6e ("media: amphion: add v4l2 m2m vpu decoder stateful driver")
