[v3,0/3] media: rkvdec: Add a VP9 backend

Message

Ezequiel Garcia May 5, 2020, 1:41 p.m. UTC

Third iteration of the VP9 stateless codec uAPI, plus
support for Rockchip VDEC.

This series addresses an issue I found while testing,
not sure how it slipped before! See patch 1.

Keep in mind the same issue should likely be fixed
on Hantro and Cedrus. We can create a helper for it
as a follow-up.

Other than that, minor documentation and smatch-detected
warnings are fixed.

Thanks!
Ezequiel
