Subject: st/nine: Fix D3DFMT_NULL size
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1f65f67b21821c00ebd9f1aa9f9f0b417b0a9677;p=mesa.git

st/nine: Fix D3DFMT_NULL size

D3DFMT_NULL is mapped to PIPE_FORMAT_NONE.
Instead of relying on PIPE_FORMAT_NONE to
return a size, pick one.
The one picked is the same than Wine.
