While finishing a rebase, I had time to do a fast port of this patch; in hopes
to spare you some time, I'm giving you my (fast) take at this.
Feel free to use it as you wish!

Subject: [PATCH] media: mtk-vcodec: Port VP9 stateless driver to upstream uAPI
This driver was written based on an old VP9 uAPI, but that code
changed over time: port this over the newest, and upstream accepted,
VP9 uAPI.
