Subject: st/vdpau: fix mixer size checks
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2cfa64e159a68998b76bdbcd20f8c7810379fce0;p=mesa.git

st/vdpau: fix mixer size checks

We need to check what the 3D pipe is able to handle for the mixer, not what
the decoder is able to decode. This fixes output of resolutions like 720x1280.
